Filton

Rotary Unions, Swivel Joints, Air Breather Filters, Flexible Hoses

(Sizes 1/2" to 1")

A suitable run-in period before fitting is recommended. Rotate the P.B. at 300 r.p.m. for 15 minutes.
Add system liquid if seals squeak.
A torque arrestor may be fitted, but this must not restrict the rotary union.
Ensure that the spindle thread is RH or LH to suit the direction of rotation of the machine shaft.
If the machine shaft reverses direction of rotation, securely lock the spindle or (preferably) use a flanged connection.
DO NOT fix valves etc. directly on to the rotary union.
DO NOT connect with rigid pipe.
DO NOT clamp the rotary union.
