Screw connection for pipes

The assembly consists of a sleeve (2) with two female cavities (3,4) which have inner conical threaded surfaces (5,6). These threaded surfaces receive the male ends (9,10) of tubes which have outer conical threaded surfaces (7,8). The male ends have non-threaded end zones (11,12) which engage with a...

More Information
Summary:The assembly consists of a sleeve (2) with two female cavities (3,4) which have inner conical threaded surfaces (5,6). These threaded surfaces receive the male ends (9,10) of tubes which have outer conical threaded surfaces (7,8). The male ends have non-threaded end zones (11,12) which engage with an inner annular passage (17) in the sleeve. The non-threaded ends of the tubes slide with a clearance inside the passage. The precise positioning of the male tube ends inside the sleeve is ensured by at least one pair of male and female stops (18,18-1,19,19-1).
