14. COUPLINGS
How to Handle Handling Couplings
1. Couplings are shipped ready-to-install... do not disassemble. To prevent gasket from
slipping out of proper position, always grasp coupling as shown in
. This will save
time by maintaining proper position of gasket and sleeve in relation to shell and flange.
Installing Couplings
1. Confirm pipe O.D. size you intend joining. Each compression coupling has been factory
inspected for proper O.D. size before shipment.
2. Be sure outside surface or pipe is dry, and free of dirt, grease or external burrs. (Burrs &
jagged pipe ends can cut gasket; dirt & grease can cause coupling slippage.)
3. Grasp coupling as shown in
to keep gasket and sleeve (and gasket protector
when used) in separate quadrants, as shown in
. Be sure gasket teeth mesh and
do not overlap.
4. Slide coupling over one pipe past end, then butt pipe ends (a small gap 1/16 maximum at
butt joint will not reduce coupling performance). Slide coupling back until coupling and
gasket protector are centered over joint. Use care when sliding coupling into place...avoid
wrinkling of gasket or gasket protector.
5. The gasket protector provides a bleed path for static electricity.
6. Partially tighten bolts evenly as follows:
1/2 bolt size - 45 ft. lbs. torque
5/8 bolt size - 65 ft. lbs. torque
3/4 bolt size - 95 ft. lbs. torque
(Where SAE GR 5 5/8 bolts are specified tighten to 95 ft. lbs. For couplings with aluminum
shell and inner sleeve do not exceed 40 ft. lbs.)
7. When properly and evenly tightened to the recommended torque the coupling installation
is complete. The top edges of the flanges will touch and flanges appear as a vee when
viewed from the end, as shown in
DO NOT
attempt tightening bolts to flatten
flange faces together, as this exceeds recommended limits.
