City Plumbing pipe bending spring for 10 mm pipe. Used on the outside of the pipe. Strong but flexible supports the pipe walls during manual bending.

• External springs are for smaller diameter copper piping ( from 6 mm to 10 mm external diameter)
• Optimal spring form prevents buckling in bending radius area
• The spring prevents the wall of the pipe from spreading outwards as it is bent
• A specific spring is required for each size of pipe being bent
