Product Description

Check valve type features internal steel ball that prevents leakage and is protected from the debris or moving parts. This thin, externally applied layer of zinc provides resistance to corrosion and can give the part a slight tint of color. Steel is a durable alloy of iron and carbon containing less than 2% carbon and 1% manganese along with small amounts of silicone, phosphorus, sulfur, and oxygen. Identical to NPTF threads, but the thread length has been reduced by eliminating one full thread from the small end of male threads or the large end on female threads.

Features:

• Taper threads begin at the shank and taper in toward the end of the fitting and mate into tapered or parallel threaded holes.
• Leakproof fittings encompass an internal rubber seal, conforming ball, or brass insert, so that grease cannot leak out when under pressure.
• The leakproof design is desirable in environments where grease can contaminate the work environment.
