Introduction

BSPP / SAE Straight

Thread Fittings Installation

Procedure

1. Lubricate O-ring with a lubricant that is com-

patible with the system.

2. Screw fitting into the straight thread port until

the metal back-up washer contacts the face

of the port.

3. Position the fitting by backing it out no more

than one turn.

4. Hold the fitting in position and tighten the

locknut until the washer contacts the face

of the port. (See

torque chart.)

NOTE:

WLN Lock

Nuts are ordered separately

by size and part n

umber.

Refer to page 73.

Face Seal O-Ring Fittings

Installation Procedure

The O-ring requires a smooth, flat seating surface.This surface must

be perpendicular to the axis of the threads.

1. Turn the O-ring seal fitting in the port until finger tight.

2. The “squeezing” effect on the O-ring can be felt during the last

1/4 turn.

3. Snug lightly with a wrench.

*Typical Application

The fitting can be adapted as a bulkhead fitting on thin wall tanks or

vessels, eliminating welding, brazing or threading. Simply order the

L5N locknut to take advantage of this option.

NOTES

• Restrain fitting body on adjustables if necessary in installation.

• Values in charts are for assemblies with O-ring lubricated.

• Use upper limits of torque ranges for stainless steel fittings.

Notes

Standard O-rings are nitrile material. For other O-rings, state mate-

rial after the part number.

L5N locknuts are ordered separately by size and part number.

Refer

to page 73.

O-rings used with SAE/MS straight threads are nitrile. Other O-ring materials are available on request. Lubricate O-ring with a lubricant compatible with the system

fluid, environment and O-ring material.
