Stainless Steel Compression Fittings Reducing Cross
Press fitting system joins pipe without welding or bolting, can be widely used in cold and hot water supply, heating supply, fire protection,medicinal gas, industrial petroleum pipeline system etc.
Standard:Press fitting standard: GB/T 19228.1-2003, DVGW W534-1995 and JWWA G116Pipe standard: GB/T 19228.2-2003,
BS EN 10312 and JIS G3448Sealing ring standard: GBT 19228.3-2003, EN681-1:1998
Technical information:
--Material: Stainless steel 304/304L and 316/316L available.
--Max working pressure 1.6MPa (equal to 232 psi),
--Testing water pressure: 2.5MPa for JIS sizes (equal to 362.5psi), and 5MPa for EN10312 sizes.
What kinds of O-Rings are suitable for your choosing ?
Option 1. CIIR(Chlorinated butyl rubber): Sanitary for human consumption, not oil resistant. Suitable for drinking water, tap water,
hot and cold water, sanitary air.
Option 2. EPDM
(Ethylene-Propylene Diene Monomer):Sanitary for human consumer, not oil resistant. Suitable for drinking water, tap water, hot and cold water, sanitary
air and compressed gas.
Option 3: FKM(Fluororubber): It is both oil proof and sanitary. suitable for edible oil, compressed air. But a little more expensive than CIIR, EPDM and NBR.
