Abstract

A low cost fitting for making joints in tubes subjected to pressure. No sealing ring needs to be forced into the tube wall and this increases the strength of the joint. The tube (1) is bulged out a short distance from its end to form rear (5) and front (4) tapering sealing faces with a straight rim (3) between. A skirt nut (14) is screwed on a female sleeve until its inside bevelled edge (18) bears against the rear sealing face of the tube. This forces the front sealing face into contact with the flared sides (9) of the female coupling. Further tightening compresses these faces to form a sealed joint. The conical end of the female sleeve receives an injection pipe.
