When cleanliness is crucial to your application, choose these fittings that are individually cleaned and bagged to prevent contamination.

With a nickel-plated finish, these compression fittings resist corrosion better than plain brass fittings.

The sleeve in these fittings is rubber instead of metal, so it cushions the tubing and absorbs vibration while creating a tight seal.

Crimp these fittings to copper tubing with a crimping tool for a leak-tight connection that doesn’t require heat or soldering. They are comparable to Viega ProPress fittings.
