Prestomatic† Retaining Ring Bulkhead Unions
Prestomatic† retaining ring bulkhead unions feature a unique design that
provides the user with an economical method to install and assemble a
union connection through a bulkhead.
The retaining ring bulkhead unions feature a smaller envelope size than
standard bulkhead union connectors and do not require a wrench to
mount or assemble in cramped areas.
The external seal feature provides a moisture barrier and can also
prevent external contamination from entering into an enclosed area.
To install, simply support the bulkhead union from behind and apply the
external seal. Then push the external retainer against the external seal
with an assembly tool and you have a reliable bulkhead connection in a
confned area.
