Stainless Steel Pressfit Flange Adapter PN25 PN16 FKM Seals 
The Stainless Steel Pressfit Flange Adapter (PN16, FKM Seals) gives engineers and installers a fast, reliable way to connect thin walled stainless steel press-fit pipework directly to flanged valves, pumps, and equipment, no welding, no open flame, no soldering required. A standard mechanical crimping tool is all it takes to create a secure, leak tight joint on 28mm OD pipe in a fraction of the time traditional methods demand.

Built from corrosion resistant stainless steel, this adapter is designed to hold up in demanding industrial and commercial environments. It converts a plain pipe end into a fully bolted PN16 circular flange, rated to a maximum working pressure of 16 bar (232 psi). At its core is a high performance FKM rubber O-ring seal, a significant step up from standard EPDM. The FKM compound handles continuous operating temperatures of up to 120°C–180°C and stands firm against oils, fuels, and aggressive chemicals that would degrade lesser seals over time.

The result is a connection that is not only fast to install but built to last. For professionals working in chemical processing, HVAC, industrial pipework, or any application where heat and chemical exposure are a daily reality, this adapter delivers the strength, speed, and seal integrity the job demands.

Summary: 

• Joins a thin walled stainless steel press-fit pipe to a flanged valve, pump, or piece of equipment
• Handles up to 16 bar of pressure and uses a high-temperature chemical resistant FKM rubber seal
• Provides high strength and resists rust or corrosion Connects to the pipe quickly using a mechanical crimping tool
• Needs no open flame, welding, or soldering
• Converts a pipe end into a bolted PN16 standard circular flange
• Fits a nominal pipe size of approximately 28 mm outside diameter (1-inch equivalent)
• Rated for a maximum working pressure of 16 bar (232 psi)
• High-performance internal O-ring seal.
• Handles elevated temperatures (up to 120°C–180°C) and resists oils, fuels, and harsh chemicals better than standard EPDM rubber

Applications: 

• Common applications include;
• Heating and cooling lines
• Compressed air lines
• Industrial fluid lines
