Seal Ring Profiles for Pipe Fittings
Square edged martensitic stainless sections for seal ring inserts
What Seal Ring Profiles for Pipe Fittings Is and Who It Is For
The profiles for the inserts in seal rings are made in martensitic stainless steels. These profiles have one special feature that governs the whole job: their square edges. A rounded edge on a seal insert leaks, so the drawing die and the inspection both focus on the corner geometry rather than on the overall size alone.
Key Benefits
- Square edges held as the controlling feature of the section
- Martensitic stainless gives a hardenable sealing face
- Consistent section means ring blanks cut from any part of the bar seal alike
- Corrosion resistance without a plated coating that can wear through
| Material | martensitic stainless steel |
|---|---|
| Key feature | square edges on the section |

How It Compares
Against an austenitic section the martensitic grade can be hardened for the sealing face, which matters where the seal is repeatedly made and broken.
Use Guide
- State the maximum permitted corner radius, not only the section size
- Confirm the hardness required after your heat treatment
- Send the mating fitting drawing if the seal geometry is critical

Questions Buyers Ask About Seal Ring Profiles for Pipe Fittings
Why martensitic stainless for seal inserts?
It combines corrosion resistance with the ability to be hardened for the sealing face.
What makes these profiles different from an ordinary section?
The square edges. That corner geometry is the controlling feature and is inspected as such.
Can you supply cut ring blanks?
Yes, bars can be cut to blank length through our machining centre.
