What Is Galling?
Galling is a type of adhesive wear that occurs when metal surfaces, like VCR-style fittings, rub together under pressure. Galling typically happens during tightening or sliding contact between the metal surfaces and may result in surface damage, material transfer, or the permanent seizure of threaded components.
What Causes Galling?
- Metal-on-Metal Contact During Assembly
- Lack of Lubrication or Protective Coating
- Over-Tightening
- Improper Alignment During Assembly
- Repeated Assembly and Disassembly
How Can You Prevent Galling in VCR-Style Fittings?
Hy-Tech’s Anti-Torque Rings
Our Anti-Torque Rings prevent gland rotation during assembly, reducing the twisting motion that contributes to galling.
Hy-Tech’s Grooved Gaskets
Our No-Overtighten Grooved Gaskets help maintain a firm seal while minimizing damage caused by over-compression.
Our Anti-Torque Rings and Grooved Gaskets extend the life of fittings, preventing them from damage while maintaining seal integrity.
