AN45074375861701-000201 Cutting Ring Coupling
Tube preparation:
- The tube (2) has to be sawn in a right angle. An angular tolerance of +1° is permissible.
- Slightly tim the pipe ends inside and outside:
For thin walled steel pipes or soft pipes made of nonferrous metal, reinforcing sleeves have to be used
Pipe assembly:
- Push union nut (4) and cut ring (3) onto Pipe (2).
- Insert pipe into Socket (5) s far as it will go and firmly press against pipe stop, otherwise incor- rect assembly.
- Hand tighten union nut (4) until socket (5), cutting ring (3) and union nut (4) are locked.
- Tighten union nut (4) 1 % turns using a spanner wrench
The cutting ring (3) is noticeably locked to the socket face. (For assembly inside pipe connection, hold up valve with a spanner wrench). This should cause the cutting ring (3) with its cutting edges (1) to cut into the pipe resulting in a visible collar. In order to stick to the tums we recommend using marking lines on union nut (4) and pipe (2).
-
After assembly, it is necessary to check the collar.
The gasket must not be damaged. At least 80% of the cutting face has to be covered. -
After check-up, screw on and tighten again as described above.
