This is a Taprite Rebuild kit for 740 series regulator.  It includes the diaphram, cartridge and thrust washer and instructions on how to repair your broken or leaking taprite regulator.  This kit fits both old and new 740 regulators with metal or plastic bonnets.  In the past Taprite made a kit for old bodies and a different kit for new bodies.  This is no longer the case.  According to the head engineer from Taprite this kit should be used for both old and new.  They old kit did not fit both, but these newer kits do!
