PTK Series Hydraulic Quick Couplings with Pressure Relief Valve Compatible with TEMA T Series
PTK Series Hydraulic Quick Couplings with Pressure Relief Valve Compatible with TEMA T Series
The PTK Series Hydraulic Quick Couplings are designed with a pressure relief valve system compatible with TEMA T Series couplings. Featuring a steel ball locking mechanism, they ensure secure and reliable connections in high-pressure hydraulic systems up to 370 bar. Constructed from carbon steel with durable Zn-Fe (Cr III) or Zn-Ni surface treatment, the PTK Series provides excellent corrosion resistance and long service life. Available with BSP and NPT threads, these couplings are equipped with NBR standard seals and optional FKM or EPDM materials for enhanced fluid compatibility. They allow connection under pressure on both sides, ensuring safe and efficient operation. Suitable for demanding industrial, construction, and agricultural applications, PTK couplings deliver superior performance, reliability, and ease of maintenance in hydraulic systems requiring frequent connections under pressure.
