Press Seal FKM
A high-performance sealing component designed for contractors working with stainless steel press-fit piping systems. Ideal for high-temperature and chemical applications, this seal ensures a leak-proof connection between pipe and fitting. To use, insert the FKM seal into the press fitting before pressing the joint with an approved tool. Its durable elastomeric design absorbs vibration and thermal expansion, maintaining system integrity under demanding conditions. Compatible with AP Stainless fittings, the FKM seal provides superior resistance to heat, chemicals, and corrosion, making it essential for chilled water, steam, air, and aggressive fluid systems.
