Parts included:

Large Diaphragm O-ring 1407-0187

Inner diaphragm O-ring 1407-0008

Seat Assembly 0740-0131

Friction Bushing 1408-0033

This will repair the SR450A, SR452A, SR450B, SR450D, SR452D, SR453D, SR450E, SR452E & SR453E.

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. 

We have other SR450 repair kits with additional parts such as the safety seat, diaphragm, cylinder fittings, etc here:
