Overview

Loctite 515 is a methacrylate-based gasket maker designed for rigid, machined metal flanges. It cures anaerobically, activating in the absence of air to form a flexible, durable seal. This medium-strength formulation helps simplify gasketing by replacing preformed gaskets and accommodates slight flange movement in service.

Key benefits

  • Eliminates the need for preformed, pre-cut, paper, rubber, and cork gaskets
  • Flexes with flanges that move in service, reducing the risk of leaks from motion or vibration
  • OEM approved for use where anaerobic gasket sealing is specified
  • Suitable for form-in-place gasketing on a range of rigid metal components
  • Medium strength with a practical fixture time for efficient assembly

Capabilities and specs

Designed for gaps and tolerances typical of machined metal surfaces, Loctite 515 provides reliable sealing without relying on air exposure. Typical fixture time is around 30 minutes, and it can seal small-to-mid sized gaps on flanges when assembled correctly. The product is formulated to maintain flexibility as flanges experience minor movements, helping to preserve a leak-free joint under varying conditions.

Typical applications

  • Water pumps and thermostat housings
  • Transmission pans and transmission case covers
  • O-ring replacement in dedicated sealing scenarios
  • Transaxle casings and other machined metal interfaces

Usage tips

  • Clean mating surfaces to remove oil and debris before application
  • Apply a continuous bead to one flange, then bring parts together within the fixture time
  • Ensure closure without air; allow time for anaerobic curing to form a durable seal
  • Check gaps and clamp correctly during assembly for optimal results

Why Loctite 515?

This gasket maker provides a practical, form-in-place sealing solution for automotive and industrial metal flanges. It offers the convenience of eliminating separate gasket parts while delivering a dependable seal that can accommodate flange movement and vibration without compromising integrity.
