Custom Vulcanized Rubber Seals for the Autoclave Pressure Vessel Industry
Quick Turnaround of Custom Spliced Vulcanized O-Rings
Whatever your rubber seal ID [inside diameter] needs are, Royal Seals is your source. Cross section capabilities to 1.5 inch and ID to 18 feet or greater. Manufactured on site with most extrusions in stock, we supply your gasket / o-rings / rubber seals fast!
Serving the autoclave industry for years, we supply rubber seals for pressure vessels – fast!
Precision Spliced Vulcanized O-Rings
We can fabricate to any specified Inner Dimension (ID), Cut Length (CL), or Custom Shape. We specialize in 45 and 90 degree angle splices, then permanently vulcanize to provide an extremely strong and uniform bond. We can make those large ID rubber seals needed for many of today’s large autoclaves.
Extrusions
Materials include: Silicone Rubber (VMQ); Fluorosilicone (FVMQ); Viton® Fluorocarbon (FKM); Perfluoroelastomer (FFKM); Ethylene Propylene (EPDM); Neoprene (CR); Nitrile (NBR); Polyurethane (EU). Tell us the material needed for your pressure vessel seals and we’ll get you a quote fast.

Manufacturing Custom Spliced O-Rings for Autoclave Pressure Vessels
Seals used in autoclave pressure vessels must withstand high pressure, high temperature, and often exposure to steam or aggressive chemicals. Because of these harsh conditions, the materials chosen for seals are highly specialized. We’ve got you covered. We’ve supplied O-rings for pressure vessels for over a decade.
Common Autoclave Pressure Vessel Seal Materials
Silicone Rubber (VMQ)
Up to ~230°C (450°F)
Excellent heat resistance, flexible, steam resistant (limited)
Applications: Lab-grade or low-pressure autoclaves
EPDM (Ethylene Propylene Diene Monomer)
Up to ~150°C–180°C
Excellent resistance to steam and water, low cost
Applications: Common in steam sterilizers and mid-range autoclaves
Viton® (FKM)
Up to ~200°C
Excellent chemical resistance, good with steam and pressure
Applications: Industrial autoclaves, especially when chemicals are involved
PTFE (Teflon®)
Up to ~260°C (500°F)
Chemically inert, excellent temp resistance, non-elastic
Applications: Often used as a coating or in composite seals
