Pump Rubber Flexible Pipe Coupling with Flange

We are a manufacturer of custom rubber products in China, providing customer with high performance custom rubber products and competitive price.

The molding processes we use is Comprssion Molding:

Taking a pr-measured amount of raw rubber material that is placed into a heated open lower mold cavity.This method can produce custom rubber products that are curved,and is usually more cheap than other molding process.

Material we use:

NBR,Nitrile,Buna-N

Silicone,VMQ

Viton,FKM, Fluorocarbon

NR, Natural Rubber

CR, Neoprene

FVMQ, Fluorosilicone
