Made of PVDF that’s finished to a 12 Ra smoothness, these fittings handle some of the harshest chemicals without leaching contaminants into your line. Comparable to Kynar, they handle most organic solvents that would dissolve CPVC, and chlorine or nitric acid that would weaken polypropylene.

Color-code fittings for easy identification. These aluminum fittings have good corrosion resistance, but are lighter in weight than brass.

Fittings have a sleeve that bites into tubing as you tighten the nut to form a seal in applications up to 120 psi. Also known as flareless fittings.

A staple in labs, these couplings are highly versatile, fitting any luer lock plug, socket, syringe, or needle. They’re PVDF, so they resist most acids, alcohols, and organic solvents.

Made of PVDF (also known as Kynar), these fittings have excellent strength and can handle temperatures as high as 240° F or 270° F.
