  • Plastic Pipe Internal Restraint Joints

Bulldog

The Bulldog Restraint System (BRS) features a metal casing holding a “S” grip in a partially conical raceway. The outer profile of the casing has sharp steps which indent firmly into the socket when it is formed using the Rieber belling process. The grip has teeth which bite into the spigot as it tries to pull out and tightens around it as it slides along the conical interface. Sealing is provided integrally in the joint by means of a high performance Rieber Metric Pressure seal.

    Thanks, Hultec for partnering up with Jet Stream and allowing us to enter the restraint joint market with the HydroGrip for C900 and IPS PVC pipe. The twenty plus year relationship we have had with Hultec, formerly S&B, has allowed us to stay a strong competitor in the PVC market.
