ISO 7421A Series carbon steel hydraulic quick coupling

Product Overview

Description

ISO  7421A Series hydraulic quick coupling stainless steel quick coupling

1. Poppet valves available to prevent uncoupled leakage

2. Ball valves   available for rugged dependability in heavy-duty hydraulic applications,within   rated working pressure            

3. Critical parts are induction hardened for   durability            

4. Dependable ball-locking mechanism holds the mating halves   together            

5. Socket and plug are precision machined from solid bar stock            

6. KZE Series couplings interchange with couplings meeting ISO 7241-1,Series   A.

This Series brings to the industry a proven   sesing for use on construction equipment,forestry equipment,agricultural   machinery,oil tools,steel mail machinery,and other demanding hydraulic   applications.
