Hydraulic Thread Sealants

Common Applications for Hydraulic Thread Sealant

Hydraulic thread sealants are essential for preventing leaks in pressurized systems where fittings, adapters, and components must be sealed against vibration, high pressure, and temperature fluctuations. These sealants protect connections by filling thread imperfections and locking components in place.

Our selection supports a wide range of industries, including:

• Oil & Gas – where thread sealants must withstand extreme temperatures and pressure
• Mobile Machinery & Equipment – to ensure durable hydraulic fittings in rugged field conditions
• Manufacturing – for use in automated systems, presses, and hydraulic assembly equipment

Sealants, Tapes, and Thread Lock Options

We offer a variety of hydraulic thread sealants and tapes to meet specific pressure, chemical, and performance requirements. Our inventory includes anaerobic hydraulic sealants such as Saf-T-Lok HS and Staybond, which cure in the absence of air and resist vibration, thermal cycling, and exposure to hydraulic fluids.

Thread sealant tapes like Unasco Gold, copper anti-seize tape, and nickel anti-seize tape provide fast, non-permanent sealing and help prevent corrosion and thread galling. We also carry pink plumber’s tape and standard white PTFE tape for general hydraulic use.
