Round HDPE UNF Threads

Threaded O-ring Plugs for UNF Threads include a compressed flange lip and an O-ring (optional) to provide a watertight seal and superior leakage prevention for hydraulic threads. The threaded O-ring keeps contaminants like dirt, dust, debris, and moisture out of the hole.

It may be installed using a hex wrench, screwdriver, or hand. Often used on flat-faced hydraulic fittings, it is recommended when strength and resistance are desired as it can withstand temperatures that range from -40F to 230F | -40C to 110C. Used in oil and gas, plumbing, and automotive sectors where leak-proof seals are crucial to system integrity.

• Material: PP, HDPE
• Colour: Yellow, Black, Red
• Material Flammability Standard: UL94 V-0

Threaded Protection Caps are designed for use with UNF and JIC Threads. Protects threads and fittings from damage during manufacturing, storage and transportation. The knurled head shape allows for easy installation and removal by hand, by simply twisting them on to the pipe or tube. Can tolerate temperatures between -30C and +80C.

• Features a knurled head design that makes them easy to install and remove by hand by twisting them onto the pipe or tube.

• If you pick the yellow option, they are made of HDPE and have a long profile, which allows for more threading turns.

• Used in various applications, including hydraulic and pneumatic systems, automotive, and industrial applications.

• Yellow option can withstand temperatures between Min. -30C, Max. +80C.

Series Code:

Threaded Protection Plugs designed for use on UNF Threads. Shield threads and fittings from damage and contaminants during production, storage and shipment. With fewer thread forms, they allow for quick application.

• It features fewer thread forms for faster application and may be applied or removed with a hand, hex spanner, or screwdriver.

• It is compatible with NS and NF Class 1-2-3 standard threads.

• Used in various applications, including hydraulic, pneumatic, and general engineering.

These Threaded Sealing Caps for UNF Threads protect threads and fittings from damage during production, storage, and shipment, ensuring that they remain in good condition and ready for use when needed. The cap is fitted with an internal neoprene rubber sealing disk to limit fluid leakage, plus it reduces potential shearing. The protection plug protects from contaminants like dirt, dust, debris, and moisture from the hole.

It is easy to install and remove by hand, but its hex head allows the plug to be applied or removed with a spanner or socket at low torque. Used in various applications, including hydraulic, pneumatic and general engineering industries.
