Connect quickly and securely

Quick connection solutions save assembly time and ensure correct installation – every time.

Quick connection

To meet a growing trend for products that can be installed quickly and easily, we have developed a quick-connection solution for the OEM industry.

A specially designed end form with two O-rings to seal the joint between the two elements. By using double O-rings, we create a more secure, guaranteed sealed connection. The pipe is held in place in the valve by a locking pin.

End forming can be performed on copper or stainless steel pipes with dimensions Ø 22 mm and Ø 28 mm

End forming for double O-rings takes installation to  a new level
  • Fast and effortless installation
  • Consistent assembly every time
  • Perfect fit with room for tolerances
  • Double o-rings for a leak-proof seal

Double O-rings for guaranteed sealed connections that allow for tolerances.
