OVERVIEW

Double sphere expansion rubber  joint ball is from the inside layer, enhanced multi-layer plastic scraper nylon cord, rubber outer layer composite tubes. Depending on the medium used rubber material is different, there are natural rubber, styrene-butadiene rubber, butyl rubber, nitrile rubber, EPDM rubber, neoprene, silicone rubber, fluorine rubber and so on. Respectively, with heat, acid, alkali, corrosion resistance, abrasion resistance, oil and other functions.

Features

Constructed of neoprene and nylon (other materials are available see charts below), the spherical shape allows pressure to exert itself uniformly in all directions, thus reducing the force exerted on pipe lines and equipment. Bias-ply tire cord provides strength, a high safety factor, and low force to move. Precision molding provides a dense, uniform carcass.
