1. Produit terminéview
Loctite 243 Blue Oil Resistant Threadlocker is a medium-strength, medium-temperature, oil-tolerant anaerobic adhesive. It is specifically formulated for general-purpose automotive and mechanical applications, providing reliable bonding even in challenging conditions.
This threadlocker effectively bonds to all metals, including stainless steel, aluminum, and plated surfaces. It is designed to secure components against heavy shock, vibration, and chemical exposure, making it ideal for rocker studs, adjustment bolts, valve and cam covers, oil pans, disc brake calipers, intakes, alternators, and pulley assemblies. It is suitable for nut and bolt applications ranging from ¼" to ¾" (6 mm to 20 mm).

3. Configuration et application
Préparation
- Shake the tube well before use.
- Clean and dry parts with Loctite Primer (Part No. 494147), if available. While Loctite 243 is oil-tolerant, clean surfaces ensure optimal performance.
- Assemble parts and make any necessary adjustments before applying the threadlocker.
Application
- Apply Loctite 243 Threadlocker directly to the threads where the nut and bolt will meet. Ensure sufficient coverage for a secure bond.
- Tighten the assembly to the recommended torque.

4. Operating (Curing Process)
Loctite 243 is an anaerobic threadlocker, meaning it cures in the absence of air when confined between close-fitting metal surfaces. It is designed for metal parts and is not recommended for plastic.
- Heure du montage : Parts will fixture (set) within approximately 10 minutes, allowing for initial handling.
- Guérison complète : The product reaches its full strength after 24 hours.
- Résistance à la température : Provides a durable, temperature-resistant bond up to 140°F (60°C).

5. Maintenance (Disassembly)
Disassembly of Medium-Strength Threadlockers (Loctite 243)
Assemblies secured with Loctite 243 can typically be disassembled using standard hand tools. No special heating is usually required for removal.
Disassembly of High-Strength or Permanent Threadlockers
For assemblies locked with high or permanent strength threadlockers, a different method is required:
- Apply localized heat to the nut or bolt to approximately 250°C (482°F).
- Disassemble the parts while they are hot.

6. Dépannage
Product Not Curing
- Ensure the product is applied between metal surfaces with minimal air exposure. Anaerobic adhesives require the absence of oxygen to cure.
- Verify that surfaces are clean and dry. While Loctite 243 is oil-tolerant, excessive contamination can hinder curing.
- Check ambient temperature. Curing times may be longer in colder conditions.
Difficulty in Disassembly
- For Loctite 243 (medium strength), standard hand tools should suffice. If resistance is high, ensure proper leverage.
- If a stronger threadlocker was mistakenly used or if the bond is exceptionally strong, refer to the heat application method described in the Maintenance (Disassembly) section.
