Product Details
✓Applications: This will repair the SR450A, SR452A, SR450B, SR450D, SR452D, SR453D, SR450E, SR452E & SR453E
✓Note: The SR460A, SR461B & SR461D models can use this repair kit since the seat is universal - but the Acetylene/Propane seats in the SR460 kits will only work for Acetylene/Propane or CGA 300 & 510 since they do not stand up to higher pressure used with other gases
✓Function: The repair kit includes the small inner diaphragm o-ring and large outer diaphragm o-ring, which are the only soft parts relating to the diaphragm that need to be replaced when rebuilding your regulator.Always clean the seat nozzle as shown in the last photo to ensure no dirt/debris/oil are present prior to completing your rebuild
✓Warning: Installation of parts should be done by a qualified technician. Improperly installed parts, debris, dirt, oil, etc. can cause malfunction and/or serious injury or death. ALL oxygen service parts and all seats should be installed with caution.Buyer assumes responsibility
✓Made of industrial-grade high-quality rubber and wear-resistant material, anti-aging, corrosion-resistant and high-pressure resistant. Long service life, effectively solve pressure drift, leakage and stuck valve problems.
