Vibra-Tite 131 Red High Strength Threadlocker - 1.8mL Tube - Suppressor, Muzzle Device & Firearm Applications The Vibra-Tite 131 Red High Strength Threadlocker is a high-strength anaerobic threadlocking compound designed to help secure threaded metal components against loosening caused by vibration, shock, and repeated use. For firearm owners, builders, and gunsmiths, Series 131 is an excellent choice for applications where a strong, long-lasting hold is desired. The compact 1.8mL tube is ideal for the gun bench, range bag, armorer's kit, or suppressor toolbox without buying a large bottle that may sit unused. Ideal for Suppressors, Mounts & Muzzle Devices Vibra-Tite 131 is particularly useful for suppressor mounting systems and firearm components where you do not want threaded parts working loose. Depending on the manufacturer's installation requirements, potential applications include suppressor mounts, muzzle brakes, flash hiders, direct-thread adapters, HUB-compatible mounting components, gas blocks, and other threaded firearm components. Its high-strength formula provides significantly more holding power than medium-strength threadlockers and is intended for components that are not expected to be routinely removed. Removal may require localized heat and appropriate hand tools. IMPORTANT: Always follow the firearm, suppressor, muzzle device, or mount manufacturer's installation instructions, including specified threadlocker, torque values, cure time, and removal procedures. Vibra-Tite 131 has a listed maximum operating temperature of 300AdegF, so it should not be assumed suitable for every suppressor component or location exposed to suppressor-level temperatures. Features High-Strength Red Threadlocker Excellent for firearm and shooting-industry applications Useful for many suppressor mounts and mounting components when manufacturer-approved Helps secure muzzle devices, muzzle brakes and flash hiders Suitable for many gas blocks and other high-vibration firearm components Helps prevent threaded fasteners from loosening under vibration and shock Anaerobic liquid formula cures between assembled metal threads 5-20 minute fixture time 24-hour full cure 200 in-lb breakaway torque Designed for threaded fasteners up to 1" Operating temperature range: -65AdegF to 300AdegF High-strength installation generally requires heat for removal Compact 1.8mL tube minimizes waste and is convenient for individual installations Specifications Brand: Vibra-Tite Product: High Strength Threadlocker Series: 131 Manufacturer Part Number: 13102 UPC: 745619131027 Color: Red Form: Liquid Strength: High Container: 1.8mL Tube Fastener Size: Up to 1" Fixture Time: 5-20 Minutes Full Cure Time: 24 Hours Breakaway Torque: 200 in-lb Removal Method: Heat / Hand Tools Minimum Operating Temperature: -65AdegF (-54AdegC) Maximum Operating Temperature: 300AdegF (149AdegC) Standards: ASTM D-5363 (AN0331), MIL-S-46163A, NSF Non-Food Red vs. Blue Threadlocker Vibra-Tite 131 Red is intended for high-strength, more permanent installations. If you expect to regularly remove or service the component, a medium-strength threadlocker may be more appropriate. For suppressors and firearms, always use the threadlocker specified by the component manufacturer. Vibra-Tite 131 - high-strength retention for firearm components that need to stay put.
