Does Boshart sell Certa-Lok Couplings?

No, we do not offer the Certa lock couplings. It makes more sense for the wholesaler / contractor to buy the Certa lock coupling along with their Certa lock pipe order. To purchase these through Boshart would add unnecessary shipping and handling costs.

What is a Certa-Lok Coupling?

A Certa-Lok coupling is a specialized, self-restraining connection device used to join sections of PVC pipe without needing glue, heat-fusion, or external metal restraints. They are manufactured in both PVC and 316 S.S. by Westlake Pipe & Fittings.

How do they work?

  • Grooves: Precision-machined grooves sit on the outside of the pipe end and on the inside of the coupling.
  • Gasket: A flexible rubber ring (elastomeric gasket) inside the coupling creates a water-tight, hydraulic pressure seal.
  • Spline: A high-strength nylon wire or "spline" slides into a hole in the coupling once the grooves align.

Key Features:

  • Bi-directional strength: Locks pipes together so they resist pulling apart or pushing in.
  • Fast assembly: Crews assemble joints in minutes using basic hand tools.
  • Trenchless friendly: Slim profiles make them ideal for pulling pipes underground during horizontal directional drilling or pipe bursting.
