Retaining Compounds & Applicators

Retaining Compounds & Applicators

Form a strong, gap-free bond between unthreaded parts with these retaining compounds to securely join the parts without machining them or using mechanical fasteners. Also called anaerobic retainers, retaining compounds remain fluid until they completely fill all the space between two surfaces and then harden due to the lack of air. These compounds evenly distribute loads along the joint to prevent pits, grooves, erosion, and other wear. They're commonly used to secure bearings, bushings, gears, sleeves, and other components to shafts or housings.

General Purpose

Use these general purpose retaining compounds to bond parts in a range of installations where you don't need a specialized retaining compound.

Applicators

Apply retaining compounds one drop at a time at any angle without leaks or mess using these hand-pump applicators. They thread onto a bottle of retaining compound and release the same amount of fluid with each drop for consistent dispensing without waste. Ideal for precision applications such as securing small parts.
