Product Description

Grease fittings (also known as Zerk fittings or grease nipples) are permanently installed on mechanical systems and bearings to provide lubrication points for feeding lubricants to the systems or bearings without overflow or leaks. The fittings stay closed to keep out contaminants until the pressure from a grease gun forces them open to allow grease to flow to the system or bearing.

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 PTF-SAE Short threads, but with one thread removed from the large end of male threads or the small end of female threads
• Standard grease fittings serve as lubrication points on mechanical components and allow a grease gun to deliver precise amounts of grease into moving systems
