Loc-tite and gas block

[jurassic]

I believe I used Loctite 620, or 609 which is designed to hold bearings, etc. at high temperature. I can see the gas tube going into the gas block through my handguard, no leaks or carbon anywhere on the gas block and barrel.


Loctite ® 609™ Retaining Compound, Cylindrical bonding


Loctite ® 609™ is a low viscosity, rapid-curing anaerobic adhesive that augments the strength of press fit assemblies or slip fit assemblies up to 0.005"in diameter. Adds up to 3,000 psi holding power. Recommended for parts that will need subsequent dismantling, i.e., retention of bearings onto shafts and into housings.
Technical Data:
Typical applications: Augment press fits
Viscosity: 125cP
Cure Time: Fixture - 10 minutes Full - 24 hours
Max gap fill: 0.12mm
Temperature resistance: 150°C
Shear strength: 15.8 /mm2

Loctite ® 620™ Retaining Compound, Cylindrical bonding, High temperature


Loctite® 620™ is a high temperature (450°F), high viscosity liquid retaining compound for cylindrical bonding .Provides a shear strength of over 3,800 psi on steel. Locks and secures metal cylindrical assemblies up to 0.015" diametral clearance. Prevents metal fretting and corrosion, Stops leakages. Typical applications
include locating pins in radiator assemblies, sleeves into pump housings and bearings in auto transmissions.
