Applications and Uses

Conex Compression fittings are especially advantageous in retrofit plumbing schemes, where space is confined and/or the use of heat must be avoided. They are available in 6-108mm and are suitable for connecting tubes in accordance with EN 1057 and many other standards including ISO 274.

Conex unique ribbed capnuts are supplied in 15-28mm. Sizes 6-12 and 35-54mm are supplied with octagonal capnuts. Fittings in 66.7-108mm incorporate loose compression plates, where tightening is through six 3/8" BSW nuts and allthreads. PTFE tape is not required for the installation process.

Conex Compression fittings are available in duplex brass and/or dezincification resistant (DZR) brass or as dezincification immune gunmetal. Fittings are also available nickel-plated or chrome plated in accordance with EN 248.

Conex Compression fittings are suitable for connecting a wide range of tubes including copper tubes in accordance with EN 1057 and many other standards including ISO 274. Fittings are also compatible with connecting low carbon steel, stainless steel and many types of plastic pipe including crossed linked polyethylene (PE-X) and polybutylene (PB) with size compatible outside diameters.
