Method 1 – Straight Edge Alignment for
Standard Sleeve Type Coupler with Black
Rubber Insert
(See Figure 7A)

Proceed with this method only if satisfied that
face and outside diameters of the coupling
halves are square and concentric with the
coupling borers. If this condition does not
exist or elastomeric couplings do not make
this method convenient, use Method 2.

1. Check angular misalignment using a

micrometer or caliper. Measure from the
outside of one flange to the outside of the
opposite flange at four points 90° apart.
DO NOT ROTATE COUPLER.
Misalignment up to 1/64" per inch of
coupler radius is permissible.

2. At four points 90° apart (DO NOT

ROTATE COUPLER), measure the
parallel coupler misalignment by laying a
straight edge across one coupler half and
measuring the gap between the straight
edge and opposite coupler half. Up to a
1/64" gap is permissible.
