What Loctite 567 is for

The general-purpose thread sealant for metal tapered threads and fittings, and the one to reach for on stainless steel. Its high lubricity prevents galling — the cold-welding of stainless threads that seizes a fitting solid — which is why it is specified across chemical processing, refining, pulp and paper, marine and gas distribution work.

Key features

Prevents galling on stainless steel, aluminium and other metal threads
Low strength — comes apart with hand tools
Oil tolerant; cures on passive substrates including stainless and plated
Certified to ANSI/NSF Standard 61 for potable water to 82°C (a regional approval)
UL classified (MH8007) for petrol, petroleum oils, natural gas, butane and propane
ULC classified to 13,790 kPa for natural gas, methane, petrol and petroleum oils
Tested to GASTEC QA AR-214 for hydrogen service (a regional approval)
Cold strength tested to −75°C

Typical applications

Steam lines
Hot water and gas

How to use it

Clean all surfaces, external and internal, with a Loctite cleaning solvent and allow to dry.
On inactive metals, or if the cure is too slow, spray with Loctite SF 7471 or SF 7649 activator and allow to dry.
Apply a 360° bead to the leading threads of the male fitting, leaving the first thread free.
Force the material into the thread roots to fill the voids. On larger threads, apply a 360° bead to the female threads as well.
Assemble and wrench-tighten in line with the fitting manufacturer's recommendations.
A properly tightened fitting seals instantly to moderate pressure; allow 24 hours for maximum pressure and solvent resistance.

Handling and storage

Not recommended for pure oxygen or oxygen-rich systems.
Not a sealant for chlorine or other strong oxidising materials.
Not normally recommended on plastics — thermoplastics can stress-crack.
Disassembly is with standard hand tools; over 1 in. diameter or long engagement may need localised heat to about 250°C.
Store unopened and dry, ideally 8°C to 21°C; outside 8–28°C the properties can be affected.
Do not return decanted product to the original container.
For potable water work, wipe away excess uncured product with a lint-free cloth and Loctite SF 7063 or similar.

Loctite 567 or 577?

Both seal metal tapered threads. 567 is the low-strength, high-lubricity grade — it is the anti-galling choice on stainless and comes apart easily. 577 is medium strength with higher torque figures and a 0.25 mm gap capability, for joints that should stay put. For plastic threads or an immediately adjustable joint, use 55.
