Equipment Safety Information
The following safety information briefly discusses hazards peculiar to the equipment, which are likely to be
encountered during maintenance activity.
COUPLER INSTALLATION AND OPERATION PRECAUTIONS
The design of the piping system must provide adequate pressure to prevent exceeding the limits of the
coupler.
Make sure the coupler orientation is correct and install the coupler in-line with the flanges. Make sure
the piping flanges are correctly positioned and spaced. Do not force the piping in order to fit the
coupler.
Make sure the coupler operates correctly after installation.
Do not exceed the pressure limits of the coupler.
COUPLER MAINTENANCE PRECAUTIONS
Do not loosen any fasteners or attempt to remove the coupler from the line until all pressure is isolated
and released from the system.
Use only authorized replacement parts or hardware.

DESCRIPTION AND OPERATION
1. Description
The Hydrant Coupler (coupler) (see Figure 1) provides the means of connecting 4-inch hydrants and
adapters conforming to API Standard 1584. The various optional configurations permit the use of
several thread and hose sizes. The major functional components of the hydrant coupler are the
swiveling outlet adapter, the elbow and the coupler body section.
2. Installation/Operation
A. Install Coupler on Hydrant
The coupler may be connected to the hydrant adapter by pressing it downward onto the adapter.
This actuates the six locking lugs, and releases the shroud. The shroud slides downward and holds
the locking lugs in their locked position. If product selection is installed, the shroud will need to be
rotated to align the product selection screws with the slots in the shroud.
B. Operate the Coupler
DO NOT OPEN THE COUPLER WITHOUT BEING CONNECTED TO AN
ADAPTER. SLEEVE SEAL DAMAGE MAY OCCUR.
After installation, to open the coupler, rotate the handle to the OPEN position. To close the coupler,
rotate the handle to the CLOSED position.
C. Remove Coupler from Hydrant
With the hydrant closed, the coupling may be disengaged from the hydrant adapter by rotating its
operating handle to the CLOSED position and pulling back the shroud to disengage the locking
lugs.
D. Remove Coupler and Elbow from Hose
Pull the safety ring from its groove and slide it back to the retaining ring. Do not remove the safety
ring. Unscrew the four retaining screws approximately 3 full turns. Slide the retainer back to the
safety ring. The elbow can now be separated from the hose.
