351GF-15 Hydrant Coupler

This installation/operation/maintenance guide is designed to

provide instructions for the installation operation & mainte-

nance/service for the Poppet Actuating Section of the Model

351GF-15 Fueling .

DESCRIPTION:

The Model 351GF-15 Hydrant coupler is a 4" size designed to

mate with hydrants manufactured in accordance with A.P.I.

Bulletin 1584. There are three basic assemblies to make a

complete connection from hydrant to hose. These are the cou-

pler shown above the ELBOW with nuts and bearing race in 4"

hydrant to 3" hose size or 4"x 4" hose.

The hose end of the elbow is fitted with a QUICK DISCONNECT

which swivels about its centerline and can be removed from the

elbow while connected to the hose.

The lower element of the coupler assembly FIG.1 is a DRY

DISCONNECT hand operated unit with an interlock (A), which is

activated by placement on an API hydrant.

The 28291-01B LOCKPIN (A) has an annular notch into which

the steel ball (B) can withdraw.

The steel ball (B) locks the 28278-01J sleeve (C) in the up or

"Poppet Closed" position which, in turn, prevents the operating

handle (D) from rotation which would open the coupler poppet (F).

As previously stated, when the "Lockpin" (A) is depressed, the

ball (B) can disengage the sleeve (C) permitting it to be pushed down.

The downward travel of the sleeve (C) drives the 12 steel balls (E)

under the lip of the API hydrant locking the device on the hydrant.

INSTALLATION & OPERATION

The 4" hydrant to 3" hose or 4" hydrant to 4" hose quick disconnect

is available on its appropriate elbow as an option with 3" NPT or

4" NPT thread sizes for hose connection.

The assembled unit is shipped with the quick disconnect &

elbow as specified for connection to the hose and placement on

the hydrant.
