Abstract
A tube connector fitting having a common body and common nuts screwed to its end, each end of the body has an enlarged portion which accepts any one of several inserts which, when inserted, comprises a sealing ring against a shoulder within the body. Different inserts are used for tubes of polyethylene and lead, steel, or copper tubing, but when copper tubing is used, its end is flared, and the flared end is clamped by the nut between a tapered backing sleeve and a tapered end surface of the relevant insert, and a very strong joint is thereby achieved. Inventory requirements are reduced since different bodies and nuts are not required for different pipes of similar size.
