The SCITEQ end closures with tie-bar model 1530 are produced purely in stainless steel. The length of the tie-bar (rod) is defined in the appropriate testing standard. For example according to ISO 1167:2006 – Part 2: The free length, lo, of the pipe between end caps shall be at least three times the nominal outside diameter, dn, with a minimum of 250mm. If, for pipes with dn greater than 315mm, the specified minimum free length, lo, cannot be achieved, a shorter free length, lo, may be chosen with a minimum of two times dn, unless otherwise specified in the referring standard or specification.

End closures with a tie-bar are produced for pipes in PE, PVC and PP. End closures are produced with a specific depth from O-ring to the internal bottom which ensures that even on chamfered and oval PE-pipes, the end closure is 100% tight while pressurising. The SCITEQ end closures with tie-bar model 1530 complies with the standards ASTM D 1598, ASTM D 1599 and ISO 1167.
