How to Build a Mixed-Material Plumbing Fittings Assortment

Brass compression straight connector for plumbing

A useful plumbing assortment is not simply a longer product list. Brass, stainless steel, PPR, CPVC and PVC-U fittings serve different connection methods and operating contexts, so buyers should group products around compatible systems.

Start with connection families

Threaded service parts can include a brass 90-degree elbow, reducing coupling and compression connector. These should be specified by thread form and sealing method, not just by appearance.

Keep press and fusion systems separate

A SUS304 press-fit equal tee uses a different installation system from a PPR 90-degree elbow or CPVC equal coupling. Present those families clearly so customers do not mix incompatible components.

Use a sourcing file

  • Connection standard and nominal size
  • Material and intended operating conditions
  • Compatible pipe system and sealing method
  • Sample, inspection and packaging requirements
