Union Couplings (Slip Type)
Union (slip type) couplings are ideal for use in confined space installations. This design allows the entire coupling to be disconnected and slipped back over the tubing to facilitate assembly and disassembly. In installations where tubing is easily assembled, it is preferable (and less expensive) to use standard straight couplings (see section 8.0). Standard material is high tensile 316 stainless steel. Standard tubing collars and glands are provided unless otherwise specified.
