Stainless One-Way Shutoff Quick Couplings (one touch type) - Male Socket and Plug are suitable for use in air compressor, pneumatic tools, automobile, car washing and shipbuilding industry. A shut-off valve in the socket prevents fluid loss in case of disconnection. Moreover, one touch design allows one-hand operation to insert the plug into the socket. Last, the knurled design of or the groove of the quick couplings features anti-slip effect.
One-way shutoff quick coupling type include one touch and tradition. One touch type includes safety, male thread, female thread, and hose series.
There are a few different materials, including SUS316, SUS304, steel, and nylon with glass fiber. Stainless features durability, corrosive resistance, high and low temperature resistance as well as anti-oxidation. Steel features longer life than products on the market. Heat treated plugs enhance the impact resistance; hardness up to HRC45 ~ 50.
Quick Couplings, also known as quick connect and disconnect couplings, quick release couplings, include one-way shutoff, two-way shutoff and two-way shutoff (grease type), one touch quick coupling, straight through type, and camlock type.
Features
- Durable.
 - Corrosive resistance.
 - High and low temperature resistance.
 - Anti-oxidation.
