2. Male stud coupling 22 mm x G 3/4 A
3. Male stud elbow 22 mm x G 3/4 A
4. Male stud tee 22 mm x G 3/4 A x 20 mm
Specifies requirements for couplings for use with tubes with outside diameters of 6 mm to 42 mm. Two types of coupling are specified, Type A where the joint is made by compressing a ring or ferrule or part of the coupling on the tube and Type B where the end of the tube is manipulated to suit the coupling.
