Quick Fit Connector Caps are designed to protect male quick-release connectors that meet SAE standards. Used in hydraulic applications to safeguard components from dust, moisture, shock damage and fluid leak residue, which could impact the hydraulic system during manufacturing, testing, storage and transport. It features a long centre tab that allows for easy removal with a strong grip, making it especially important for fluid applications.

This series is manufactured from Post Consumer Recycled material, which is designed to support Essentra’s ESG ambitions and those of our customers. Material: LDPE - PCR Colour: Green Series Code: SRQCFPCR

Slotted Plugs are designed with a double sealing ring on the underside of the flange that provides a secure and reliable seal. The design includes five complete threads for a secure fit. Offers protection from dirt, dust, debris, liquid residue and corrision. Head designed not to trap liquid when the plug is secured in place.

These Sealing Plugs are easy to install and remove by hand. The hex head design allows the plug to be applied or removed with a screwdriver, spanner, Allen key or socket. The range covers an extensive offering of dimensions suitable for Metric, BSP, and UNF threads.

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

Wide Flange Threaded Protection Plugs shield threads and fittings from damage and contaminants during production, storage and shipment. The nitrile gasket ensures a leak-tight seal against the mating surface. The wide flange prevents paint flakes from entering the hole upon removal. Withstands intermittent temperatures from -40C up to +100C.

• Its wide flange design keeps any paint flakes from the hole when removed.

• Their nitrile gasket seals the plug to the mating surface for leak-tightness.

• It is recommended for intermittent temperatures from -40C to +100C.

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.
