The Diaphragm is a tough,flexible seal with a unique configuration that permits relatively long piston strokes while completely eliminating sliding friction.

 Formed in the shape of a truncated cone, or top hat, the diaphragm is turned in on itself when installed so that, during the stroke, it rolls and unrolls alternately on position skirt and cylinder wall. The rolling action is smooth and effortless, completely eliminatinf sliding contact and breakaway friction

1. Application: Pump& Valve; Auto instrument; Pneumatic parts; Gas equipment; Electronic products; Electric equipment; Air &Liquefy Products .

2. Compound materials: Reinforced fabric (Nylon.polyester.Fiberglas.Nomex and other reinforced fabric) as the skeleton coated with the rubber elastomer (NBR.NR.EPDM.FKM.Silicone and other special elastomer) one side or both sides. Thickness (0.2-0.5mm) and elastomeric is different according to special requirement.

3.Character :high breaking strength, high tensile strength ,high resistant to oil ,acids ,alkalies  and other corrosives fluids, ageing-resistance ,long life ,good at sealing .
