Bulkhead Locknut Assembly

A bulkhead fitting allows one to connect tube or hose through a

panel.This panel, often referred to as bulkhead, may be a struc-

tural element of the equipment, or an additional plate which is

joined to the equipment, to facilitate convenient routing of hose

and tube. Bulkhead fittings are also used as a transition point

in a hydraulic system, such as connection of tube lines to hose

lines or to a quick disconnect coupling.

The following steps are recommended for the proper assembly

of the locknut for Triple-Lok, Ferulok and Seal-Lok bulkhead

fittings.

1. Drill a pilot hole to dimension W + 0.015” (where W is

shown in Tables T27 an

d

T28

).

2. Insert the bulkhead end of the fitting (without the locknut

assembled) through the bulkhead opening and attach the

locknut to the bulkhead end.

3. Finger tighten the locknut and wrench tighten further to

the recommended torque shown in Table T27 for Seal-Lok

fittings or

Table T28

f

or Triple-Lok and Ferulok fittings.

* Recommended clearance hole is W + 0.015”

Pipe Swivel Assembly (NPSM)

Unlike traditional pipe thread, these connections seal on the

nose of the swivel end. The nose has a 60° inclusive angle

that mates against a chamfer of the same angle on the male

pipe thread end (also known as a 30° chamfer).

adapters seal on mating
