620 Retaining Adhesive

Loctite 620 is designed for bonding cylindrical fitting parts. It prevents loosening and leakage caused by impact and vibration. Typical applications include positioning pins in radiator assemblies, sleeves in pump housings, and bearings in automatic transmissions. This product can withstand temperatures up to 230°C, with strength increasing as the temperature rises. For steel applications, it can achieve a shear strength of 3800 psi. The product is suitable for cylindrical assembly operations with a fitting clearance of less than 0.2 mm. It prevents fretting wear and corrosion in metal assembly operations, while also preventing leakage, and is certified by DVGW (EN751-1).
