Installation Guidelines - Joint Assembly
Step 1
Loosen No-Hub coupling outer band bolts until the inner plastic body moves freely.
Step 2
Inspect coupling inner plastic body; clean out all cement dust, mud or other debris
from the inner body surface with a clean cloth sprayed with 90% isopropyl alcohol.
Step 3
Insert the pre-grooved pipe or fitting end into the coupling inner body until the
coupling ridge can be felt snapping into place in the groove. Sliding the outer
band back from the inner body may make this easier. The ridge must seat into the
groove to ensure proper fit, seal the joint, and prevent pullout.
Step 4
Position the coupling outer steel band such that it is centered over the inner
coupling body; the inner body should be equally visible at each edge of the outer
band.
Step 5
Using a 5/16" socket with a torque wrench, or using the Orion supplied T-handle
torque wrench, torque each band to 60 in/lbs making sure to alternate between all
bands keeping pressure even. After torquing, check each band. Check the torque
by applying the wrench and clicking once more. Each band should be double
checked. Alternate tightening each bolt to ensure even pressure is applied to both
sides of the coupling; fully tightening one side before tightening the other, especial-
ly if using a power tool like an impact wrench, can cause the resulting joint to leak.
Step 6
If during testing a leak is found, loosen the outer band and turn 90 degrees and
re-tighten following previous applicable steps.
NOTES
Satisfactory installation requires careful measurement.
Cheating on pipe lengths will cause a bind, allowing joints to leak even when fully
tightened.
All No-Hub joint components must be kept clean prior to and during assembly.
Mud, dirt, cement dust or other foreign matter in joints is the most common cause
of failure.
Both over-tightening and under-tightening No-Hub couplings can result in leaks.
