Product Description


China National Standards Drafting Unit of Rubber Joint
Qualified Joint Supplier in Nuclear Power Plant

DN35~5000mm single-ball flanged rubber coupling feature rugged yet flexible polyester cord fabric reinforcement ,  to ensures an exceptional burst pressure rating.
The streamlined flowing arch design reduces turbulence and allows smooth, quiet flow-no need to fill the arch and restrict its movement.
