Product identity and purpose

Rectorseal Moly-Rich 71431 is a premium anti-seize lubricant formulated with molybdenum disulfide and extreme-pressure additives in a grease base. It protects threaded assemblies from seizure and heat-freeze across a service range of -65°F to 2400°F and resists water wash-off for outdoor use.

Suitable trades and limitations

The compound suits HVAC, plumbing, electrical and construction professionals who need reliable breakout up to 1050°F and a lubricant that will not harden, evaporate or settle out. It must not be used on stainless steel exposed to temperatures above 550°F or in oxygen service environments.

Behaviour under sustained load

The formulation withstands vibration and thermal cycling without hardening, dripping or separating, maintaining consistent friction reduction during prolonged high-temperature exposure. Rust and corrosion inhibitors remain active throughout the 2400°F upper service limit, preserving thread integrity over extended duty cycles.

Questions about this item

What thread size or fitting type do I need to match the 1 lb container's opening for dispensing?

The container measures 3.25 by 3.25 by 4.5 inches with a 0.54 kg net weight; it uses a standard wide-mouth jar opening that accepts a putty knife or brush for scooping the molybdenum disulfide grease.

Can I apply this anti-seize on stainless-steel bolts that will see 550°F in service alongside older copper-based compounds?

Do not use on stainless steel above 550°F (288°C); the molybdenum disulfide formula is lead, copper and zinc free, so it will not galvanically attack stainless, but temperature limit still applies.

How do I verify the lubricant is still effective after storage and initial assembly?

The grease will not harden, evaporate, run, drip or settle out; smooth consistency and low coefficient of friction up to 1050°F (566°C) confirm it is working.
