You don\u2019t see it. You don\u2019t brag about it. But if it\u2019s missing\u2014or not doing its job\u2014you\u2019ll know fast.<\/p>\n\n\n\n
Let\u2019s be honest: nobody wakes up excited to talk about gaskets. Well, except maybe for Mark Knapp.<\/p>\n\n\n\nMark Knapp<\/figcaption><\/figure>\n\n\n\n
When a drainage job goes right, the pipe gets the credit. When a job goes wrong, the pipe still gets blamed. And somewhere in the middle\u2014quiet, unnoticed and absolutely critical\u2014is the gasket. It\u2019s the small component doing the big work: keeping water where it belongs, holding the joint together and helping systems perform for years after the heavy equipment has left the field.<\/p>\n\n\n\n
That \u201clittle\u201d part is exactly where SpringSeal Inc. has built its name.<\/p>\n\n\n\n
Founded in 2003 by Mark Knapp, SpringSeal designs and manufactures gasket systems and sealing solutions\u2014most notably for corrugated pipe. Knapp has been in the pipe and gasket world since the late 1980s, and he\u2019s spent decades focused on one mission that\u2019s simple to say but hard to pull off: make pipe joints seal better, assemble more consistently and perform longer out in the real world.<\/p>\n\n\n\n
\n
A lot of people don\u2019t think about pipe at all. But there\u2019s a lot that went into making that pipe\u2014and our part is making sure that doesn\u2019t leak.<\/p>\n<\/blockquote>\n\n\n\n
A Company Built on Details That Matter<\/h2>\n\n\n\n
SpringSeal started with extrusion. In the early days, Knapp\u2019s team extruded gasket profiles and fused them \u201cendless\u201d to create finished gaskets for pipe ends. But the company didn\u2019t stay small\u2014or single-process\u2014for long.<\/p>\n\n\n\n
Today, SpringSeal manufactures across multiple production methods, including extrusion, injection molding, thermal forming and fabrication. The business has expanded from one extrusion line to sixteen, and it now produces over 600 products across multiple industries including pipe, marine, architecture and transportation. Even with that diversification, pipe remains the company\u2019s core. Knapp estimates pipe-related work still accounts for about 80% of what they do.<\/p>\n\n\n\n
SpringSeal currently employs 84 people, most of them on the manufacturing side, with a smaller office and management team supporting engineering, quality and operations.<\/p>\n\n\n\n
Growth, for SpringSeal, hasn\u2019t been about being bigger just to be bigger. It\u2019s been about having the capability to solve problems that pipe manufacturers and contractors actually face\u2014especially when conditions aren\u2019t perfect.<\/p>\n\n\n\n
The “You Don’t See It” Part That Makes Everything Work<\/h2>\n\n\n\nThis gasket splicing press joins the ends of each gasket into a continuous ring.<\/figcaption><\/figure>\n\n\n\n
Gaskets have to keep sealing season after season\u2014through temperature swings, exposure, settlement and all the other realities of buried infrastructure. That\u2019s why gasket design isn\u2019t just rubber shaped into a ring. It\u2019s material science, geometry, installation consistency and long-term durability all packed into something most people never notice.<\/p>\n\n\n\n
This is where SpringSeal\u2019s work has helped push the industry forward.<\/p>\n\n\n\n
Knapp explains that early in SpringSeal\u2019s history, the company developed what he describes as the beginnings of the dual-durometer gasket program used by many corrugated pipe companies today\u2014designs that combine materials with different hardness and flexibility characteristics to improve performance.<\/p>\n\n\n\n
Back in those early years, it wasn\u2019t just a matter of making a gasket that fit. The goal was to improve the entire joint system\u2014how it assembled, how it sealed and how it held up over time.<\/p>\n\n\n\n
\u201cIt was the very beginning of one of the first gasket systems like its kind in the industry,\u201d Knapp says. \u201cIt showed higher, better performance and definitely improved the pipe industry.\u201d<\/p>\n\n\n\n
Early Work With Fratco<\/h2>\n\n\n\n
SpringSeal\u2019s relationship with Fratco goes back a long way\u2014before SpringSeal even had its name on the door.<\/p>\n\n\n\n
Knapp had worked with Fratco through a previous company while supplying gasket systems, during a time when Steve (Chris\u2019s father) was president. When Knapp founded SpringSeal in 2003, Fratco continued that working relationship and grew alongside the new venture.<\/p>\n\n\n\n
\u201cFratco was one of the first companies we worked with,\u201d Knapp says. \u201cWe decided to give it a shot.\u201d<\/p>\n\n\n\n
Over the years, that partnership has remained steady\u2014built on communication, shared goals and a commitment to quality products in the field.<\/p>\n\n\n\n
For Fratco, SpringSeal also provides gaskets with a recognizable red stripe\u2014a simple detail with real value. It helps identify products in the field and supports branding at the point where contractors and distributors actually interact with it.<\/p>\n\n\n\n
Solving the Installation Challenge<\/h2>\n\n\n\n
Even the best pipe on the market can only perform as well as its joint. And consistency in the field matters.<\/p>\n\n\n\n
Installations vary. Crews move at different speeds. Weather changes. Conditions aren\u2019t always textbook. SpringSeal works to reduce variability wherever possible\u2014designing products that help ensure joints go together smoothly and perform reliably once they\u2019re buried.<\/p>\n\n\n\n
One example is SpringSeal\u2019s pre-lubricated gasket film\u2014a thin, wear-resistant coating applied over the gasket through a proprietary process referred to as slip coating.<\/p>\n\n\n\nThe Profile 360 takes thousands of measurements per second to continuously monitor the dimensions of the product passing through.<\/em> <\/mark>The Profile 360 takes thousands of measurements per second to continuously monitor the dimensions of the product passing through.<\/em><\/mark><\/figcaption><\/figure>\n\n\n\n
\u201cIt lowers the coefficient of friction,\u201d Knapp explains. \u201cIt makes it have a lubricated feel\u2014even though it can\u2019t be wiped off.\u201d<\/p>\n\n\n\n
The practical benefit is simple: more consistent assembly. In some cases, the film can significantly reduce the amount of additional lubrication needed in the field.<\/p>\n\n\n\n
\u201cIt assures the pipe gets assembled properly,\u201d he says. \u201cIt still will go together because the gasket has this lubrication film on it.\u201d<\/p>\n\n\n\n
It\u2019s a small adjustment that can make a big difference in real-world conditions.<\/p>\n\n\n\n

Engineering Mindset: Building the Equipment, Not Just the Product<\/h2>\n\n\n\n
SpringSeal isn\u2019t only a gasket manufacturer\u2014it\u2019s a company that treats manufacturing itself as an engineering problem to solve.<\/p>\n\n\n\n
Knapp notes that SpringSeal builds much of its own equipment in-house, including fusion and downstream systems. That approach allows the company to control its processes, protect proprietary methods and move quickly when improvements are needed.<\/p>\n\n\n\nSpringSeal\u2019s thermoforming machine heats, molds, trims and finishes material all in one machine.<\/mark><\/em><\/figcaption><\/figure>\n\n\n\n
\u201cWe design all of our own equipment here,\u201d Knapp says. \u201cWe build machines from the ground up.\u201d<\/p>\n\n\n\n
That mindset pairs with robust quality assurance systems. SpringSeal uses laser-based measurement equipment that continuously monitors gasket profiles as they run\u2014capturing thousands of measurements per second and flagging when production trends toward out-of-spec.<\/p>\n\n\n\n
To keep throughput high, SpringSeal also runs multi-strand production methods, producing multiple gaskets simultaneously before separating them later in the process. The result is high capacity without sacrificing consistency.<\/p>\n\n\n\n
Patents, Progress and Partnership<\/h2>\n\n\n\n
Innovation is more than a buzzword at SpringSeal. Knapp reports the company operates under approximately 26 active patents, reflecting ongoing development and refinement across sealing applications.<\/p>\n\n\n\n
But what stands out most in Knapp\u2019s perspective isn\u2019t just technology\u2014it\u2019s the culture of the industry itself.<\/p>\n\n\n\n
\u201cMost of my customers are all my friends,\u201d he says. \u201cEven my competitors\u2026 we don\u2019t share secrets, but we still communicate. We\u2019re all trying to make it better for the industry.\u201d<\/p>\n\n\n\n
When asked how SpringSeal\u2019s values align with Fratco\u2019s, Knapp comes back to the basics: shared goals, shared commitment to quality and being there when problems need to be solved.<\/p>\n\n\n\n
\n
We\u2019re goal oriented. We want improvements to the industry and to our products. We\u2019re here to help them when they have an issue.<\/p>\n<\/blockquote>\n\n\n\n
And when asked what the best benefit of working with Fratco has been?<\/p>\n\n\n\n
\u201cVery easygoing,\u201d he says. \u201cVery few issues. We work very well together. It\u2019s been a pleasure.\u201d<\/p>\n\n\n\n
The Takeaway: Small Part, Big Job<\/h2>\n\n\n\nSpringSeal\u2019s gaskets play a pivotal role in sealing the HDPE pipe seen here, laid out for stormwater management.<\/em><\/mark><\/figcaption><\/figure>\n\n\n\n
Gaskets aren\u2019t glamorous. They aren\u2019t the part customers point to in a field or jobsite. They aren\u2019t what gets discussed at the front of the room when a job is celebrated.<\/p>\n\n\n\n
But if you\u2019ve ever dealt with a leaky joint, an inconsistent assembly or a repair that needed to work the first time\u2014then you already understand how important that \u201cinvisible\u201d piece really is.<\/p>\n\n\n\n
SpringSeal has spent more than two decades making sure that invisible piece does its job\u2014quietly, consistently and for the long haul.<\/p>\n\n\n\n
And in a world where water always finds the weakest point, that\u2019s not a small thing.<\/p>\n\n\n\n
