Product Description

Grease Fittings (Zerks) are small one-way valves used to allow easy lubrication of bearings and joints. PTF Threads are most often used on heavy machinery in the construction and agricultural industries.

Features:

• Check valve type features surface ball provides leak-free performance
• 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
• Taper threads begin at the shank and taper in toward the end of the fitting and mate into tapered or parallel threaded holes
• Standard grease fittings serve as lubrication points on mechanical components and allow a grease gun to deliver precise amounts of grease into moving systems
