N.B.:

When using a socket spanner, the torque must not exceed that of the thread

(e.g. fitting XR1 Ø 4 1/8”, with a 3 mm thread, has a maximum torque of 6 Nm,

highest value of the thread)

INSTALLING THE PIPE

Compressed air pipes must be used in compliance with some basic criteria in order to ensure long life and proper operation of the fitting:

• check that the conditions for the installation and use (e.g. temperature and fluid used) comply with the characteristics stated by the pipe

manufacturer;

• check the pipe size; oversized pipes could not fit properly, undersized ones could not ensure pipe retention and air tightness.

The cut should be as accurate as possible at a right angle with the pipe axis.

• the bending radius of the pipe installed must be as wide as possible. The fittings have been designed to ensure axial seal of the pipe; excessive

curvature could considerably shorten the life of the pipe.

• the pipe must not be subjected to excessive axial stress and it must be of the right length for snugly fitting (not too long or too short).

• correct insertion of the pipe into the fitting is essential for air tightness and pipe retention. Make sure that the pipe is pushed right into the seat.

• check that the pipe does not encounter any obstacles or blockages along its way, which could cause tensile stress of the pipe in the fitting.
