La description

The male body is hardened for long life. Our models are manufactured to comply with the ISO ***5, SAE J ***6, and ISO ****-A/B international standards. Pimak hydrolic quick couplings are manufactured in 1/4", 3/8", 1/2", 3/4", 1.1/2", *1/4”, 2" BSPP sizes as standard. Metric and NPTF threads are available on request. The valve of the Pimak couplings is specially constructed to prevent external leakage during the most arduos operating conditions. The valve stop is machined from luminiumalloy to withstand the forces exerted by high flows whilst still maintaining very low pressure drops. Nitrile O-ring seals with ptfe back up rings are used througout as per the ISO, SAE, and TS standards. Silicon rubber or viton seals can be fitted on request. Also we use teflone backup ring in our couplings. Pimak hydraulic quick couplings are designed to withstand 4 times the recommended operating pressure. Every component is tested to double the operating pressure for leakage.
