Stainless Steel Hydraulic Quick Connect Couplings Female Thread KZF ISO7241-B

 the KZF Series Hydraulic Quick Couplings is a special series that design for some water applications, All this series material is s304 stainless steel, and with a ZG female thread, and they all comply with ISO7241 B Standard.
KZF Coupler is an ISO B quick coupling, the body size is 1″ that means it is interchangeable with any other ISO B quick coupling 1″ body size from other manufacturers.
KZF body material is Stainless steel 304, usually, it is used in some water fluid hydraulic equipment or some fluids that easy to oxidize the body material, the stainless steel can supply better anti-corrosion performance.
The disadvantage of the stainless steel material is that they cannot supply high-pressure performance because of its structures. The Seal ring is NBR, but you can ask us to supply with Viton FKM.

What are Quick Coupling

Hydraulic quick couplings provide users with the ability to rapidly connect and disconnect hydraulic hoses to machines or other sections of plumbing. Also called quick-connects or quick disconnects, these fittings allow fluid to flow when the male and female sides are locked together. Conversely, when disconnected, the quick couplings prevent fluid leakage using check valves to block exiting fluid.

Quick connect couplers are manufactured by multiple manufacturers and can be often interchanged. Longwei supplies the highest quality hydraulic quick disconnect couplers such as flushface, ISO A, ISO B, wingnut, Ag, and Skid Steer.

Profiles of male nipples help you to identify four popular styles of hydraulic quick disconnect couplers in nominal sizes ranging from 1/4" to 1". Nominal sizes represent intended hose or tube sizes, not the actual diameter of the coupler.
For actual dimensions, print this page actual size and compare the profile drawings to your existing equipment.
