Stainless Steel PTFE Seals for High Pressure and Chemical Resistant Systems

Sometimes, the smallest component in a machine ends up being the one that keeps
everything else working. That’s usually the case with stainless steel PTFE
seals series. They don’t get much attention—until something goes wrong.

In our work, especially when dealing with pressure systems or chemical
exposure, we needed something that didn’t just “fit,” but kept performing.
That’s how we came to use these stainless PTFE seals. Not a new invention, but
when combined properly, they hold up far better than most alternatives.

You’ve got PTFE, which helps with friction and chemical resistance. That
part’s straightforward. What’s often overlooked is how it behaves under
stress—especially heat and mechanical load. That’s where the stainless core
comes in. It gives shape. Holds structure. Keeps things aligned even after
hours of operation.

We’ve used these seals in pumps, motors, and rotary machines. Also in places
where cleaning fluids or pressure cycling tends to kill rubber-based parts.
They’re not magic. But when you choose the right shape—sometimes spring-
loaded lips, sometimes a flanged edge—they tend to last.

We keep a fair amount of types in stock. If a customer calls with a rush job,
we usually have a workaround or a close match. For special cases, we work
through sketches, simulations, sometimes just a quick call. We've got teams
that know how this stuff behaves.

The seals we send out usually fall within -65 to 260 degrees C. That’s enough
for most systems we touch. Pressure? Depends. But 30 or 40 MPa isn’t out of
range in static use. That said, we always recommend testing in the real setup.

A lot of what we do isn’t about selling seals. It’s helping engineers avoid
problems later on. When you choose a design early that matches real working
conditions—not just catalog specs—you end up with fewer breakdowns, and fewer
callbacks.

That’s what we aim for.
