Anaerobic Gasket Maker 50 mL

Loctite 135474 is a pink anaerobic gel designed to form rigid gaskets between metal flanges. It cures in the absence of air when confined between close-fitting surfaces. The product suits mechanics and maintenance teams assembling gearboxes, engine casings or pump housings where conventional cut gaskets are unavailable or impractical.

Gap fill limited to 0.01 in

The anaerobic chemistry only cures effectively when the joint gap does not exceed 0.01 in. Larger gaps remain uncured and compromise sealing integrity. Full cure requires 4 hr at room temperature, during which the assembly must stay clamped and undisturbed. Working time is 25 min, giving a short window for positioning parts before the gel begins to set.

Service range -65 °F to 400 °F

The seal remains functional across a continuous temperature span from -65 °F to 400 °F. This range determines suitability for high-heat engine environments or sub-zero outdoor equipment. Exposure beyond these limits will degrade the cured material and cause leakage. The product carries California Proposition 65 warnings for cancer and reproductive harm.

Questions about this item

Is the 50 mL tube the only size offered for this anaerobic gasket maker?

The listing shows a single 50 mL (1.69 fl oz) tube; no other container sizes are mentioned.

What does the 400 °F maximum operating temperature mean for an assembled joint?

The cured seal remains stable up to 400 °F and down to -65 °F, so the joint can handle typical engine and exhaust heat cycles.

How does the anaerobic cure work on metal flanges?

The gel cures in the absence of air between metal surfaces, reaching full strength in 4 hours with a 25-minute working time and filling gaps up to 0.01 in.
