Threaded Sealing Caps
Protect and limit fluid leakage with Essentra UNF/Metric threaded sealing caps. These yellow high density polyethylene caps cover unified threads from 1/4”-28 to 1-7/8”-12 and metric threads from M8x1 to M52x2.

The HDPE material is resistant to solvents and reduces the potential for shearing. The cap includes a neoprene sealing gasket to limit fluid leakage. The hexagonal head enables the application or removal with a wrench or sock at low torques but it is recommended to tighten by hand. Essentra stocks and is ready to ship 42 different standard threaded sealing caps at our strategically located regional distribution sites. [more][less]
