LOCTITE® 565 PST Thread Sealant – 50ml / 250ml

🔧 Premium Pipe Thread Sealant for Metal Fittings – Vibration & Leak Resistant

🛠 Product Overview

LOCTITE® 565 PST Thread Sealant is a white to off-white, high-viscosity anaerobic sealant engineered for locking and sealing metal threaded pipe fittings. It provides a low-strength, methacrylate-based bond that cures in the absence of air between close-fitting metal surfaces. This formula offers reliable resistance against shock, vibration, and pressure leaks, making it ideal for both maintenance and OEM applications.

✅ Key Features & Benefits

• Reliable Thread Sealing for Metal Pipes
  Specially formulated for sealing metal threads in hydraulic, pneumatic, and industrial systems.

• Anaerobic Cure for Maximum Sealing
  Cures in the absence of air when confined between close-fitting threads, creating a durable, leak-proof seal.

• Low Strength – Easy Disassembly
  Allows for convenient maintenance or adjustment without damaging threaded components.

• High Viscosity for Controlled Application
  Thixotropic nature ensures excellent gap-filling and prevents migration after application.

• Prevents Leakage & Vibration Loosening
  Locks fittings securely while resisting loosening caused by shock, thermal cycling, or vibration.
