Some components just need to do their job—quietly, without fuss. PTFE stainless steel shaft seals fall into that category. You won’t notice them when they’re working, but you definitely will when they fail. Especially in systems under pressure, heat, and constant use.
DEDE makes PTFE stainless steel seals seals for those situations. The ones where most materials give in. Ours don’t.
So, what’s the big deal with PTFE and steel?
You’ve probably heard of PTFE—it’s used everywhere from lab gear to piping systems. The reason? It doesn’t react. And it slides. Now, take that and reinforce it with a stainless steel core. Suddenly, that soft, slick material has backbone. Literally.
We use 304 or 316 stainless. It’s not just about strength—it’s about shape retention. When the pressure’s on, your seal needs to hold form. PTFE helps it resist the media, steel keeps it in place.
Where Do These Seals Belong?
They’re not for everyday plumbing. Think harsher stuff:
· Acid lines in a chemical plant
· High-RPM shafts in engines
· Steam circuits in a power system
If your seal fails and the process halts, this is the kind of solution to look at.
A Few Technical Bits (because someone will ask)
· Temp range? -65°C to +260°C
· Pressure? We’ve tested them to 40 MPa
· Chemicals? Most acids, fuels, solvents, yes
· Wear? Better than anything we’ve used before
What You Actually Get
Not just a product. You get:
· Parts ready to ship—over 10000 SKUs on-hand
· A team who’s done this 30+ years
· Real testing—not just charts on paper
· Custom work if the standard won’t cut it
This isn’t a copy-paste solution. If your equipment is unique, we’ll make the seal match it—not the other way around.
If a small part can shut down your line, better make it a good one.
DEDE is PTFE stainless steel shaft seals were built to outlast the rest. We
know. We’ve seen them do it.
