Washers for API Clamps
Why do we need to use washers on the clamp securing
our flexible manifold hose?
We assume you have an armored flexible hose with an
API clamp hub, and
you may have a WOODCO USA made clamp to connect it to another piece of
equipment. The washers supplied by WOODCO USA, with each clamp sold,
assure that each tightened nut on the clamp will have flat bearing
against the clamp nut seating surface.
Clamp installation often results
in the gap between clamp halves differing on the two sides causing the
nut bearing surfaces to lack parallelism. Specially designed "Spherical
Washers", two installed in proper order under each nut, corrects for the lack of parallelism and
equalizes the load on the tightened nuts.
For specific instructions on clamp installation and correct installation
of washers, see
