Key specifications
Type: circular sealing O-ring for plug seal
Compatibility: designed for WELDLINE WTT17 plug assemblies
Function: prevents fluid or gas leaks at the plug interface
Application area: welding equipment connectors and plugs
Material characteristics: elastomeric sealing material suitable for connector sealing (standard for industrial welding seals)
How to use
Before installation, inspect the plug housing and mating surfaces for debris, wear or damage. Remove the old O-ring carefully and clean the groove using a lint-free cloth and an appropriate solvent if necessary, then allow surfaces to dry. Place the new O-ring into the groove ensuring it sits evenly without twists. Reassemble the plug and test the connection under operating conditions to confirm there are no leaks and that the seal performs correctly.
Usage recommendations
Store replacement O-rings in a cool, dry place away from direct sunlight and ozone sources. Replace O-rings at the first sign of cracking, hardening or deformation. Use only compatible lubricants recommended for elastomer seals when fitting to avoid material degradation.
