Bill of Materials
1. Apply a thin coat of approved lubricant to the bottom surface
of the bullplug pressure relief device (PRD) port.
2. Install seal washer into the bullplug PRD port.
3. Install shear disk (with markings facing upwards) into the
bullplug PRD port.
4. Apply a thin coat of approved lubricant to the threads and
face of PRD plug.
5. Screw PRD plug into the bullplug PRD port and torque to
250 ft/lbs.
NOTE 1: Steps 6-8 apply to "Option 1" and "Option 2" only.
NOTE 2: Fusible metal option requires factory assembly.
6. Screw the jam nut clockwise onto the 1 3/8"-12UN threads
of the angle block until the nut stops at the back face of the
angle block. Install the angle block into the bullplug threads.
7. Configure the angle block to correct position to install vent
tube and hand-tighten the jam nut against the bullplug.
NOTE: The angle block should be no less than five (5) full
turns into the bullplug after configuration of the vent tube.
Six (6) turns into the bullplug is the optimum engagement.
8. After configuring the angle block for the vent tube, torque
the jam nut into the bullplug at a torque of 100 ft/lbs. NOTE:
A back-up wrench should be used to secure the angle block
while the jam nut is tightened to final torque.
NOTE 3: A weather membrane shall be installed with RTV sili-
cone to ensure a weatherproof seal.

M76 Series Bullplug Assembly
Internal Plug with Pressure Relief Device
Bill of Materials
1. Apply a thin coat of approved lubricant to the bottom surface
of the bullplug pressure relief device (PRD) port.
2. Install seal washer into the bullplug PRD port.
3. Install shear disk (with markings facing upwards) into the
bullplug PRD port.
4. Apply a thin coat of approved lubricant to the threads and
face of PRD plug.
5. Screw PRD plug into the bullplug PRD port and torque to
250 ft/lbs.
NOTE 1: Steps 6-8 apply to "Option 1" and "Option 2" only.
NOTE 2: Fusible metal option requires factory assembly.
6. Screw the jam nut clockwise onto the 1 3/8"-12UN threads
of the angle block until the nut stops at the back face of the
angle block. Install the angle block into the bullplug threads.
7. Configure the angle block to correct position to install vent
tube and hand-tighten the jam nut against the bullplug.
NOTE: The angle block should be no less than five (5) full
turns into the bullplug after configuration of the vent tube.
Six (6) turns into the bullplug is the optimum engagement.
8. After configuring the angle block for the vent tube, torque
the jam nut into the bullplug at a torque of 100 ft/lbs. NOTE:
A back-up wrench should be used to secure the angle block
while the jam nut is tightened to final torque.
NOTE 3: A weather membrane shall be installed with RTV
silicone to ensure a weatherproof seal.

M25 Series Pressure Relief Device
Integrated Bullplug / Valve Assembly
Manufactured from 304L stainless steel.
FIBAs integrated bullplug/valve assembly is designed especially for jumbo and
superjumbo tube trailers to enhance safety, reduce leaks, and insure compliance with
CGA TB-25. (It can also be used on multiple-element gas containers.) The innovative
design protects the valve internal components from damage or leakage in the event ofa rear end collision or rollover. The valves sacrificial hand wheel has a machined shear
point to allow shearing with no damage to the valve internal, pressure-containment
parts. A simple replacement of the hand wheel gets the valve operational within
minutes to allow unloading of the gas and safe evaluation of the accident damage.
The CGA 580 outlet connection is machined directly into the face of the bullplug
to eliminate costly thread leaks, which are common in tube isolation valves. The
bullplug body is manufactured from 304L stainless steel and, thus, should never need
replacement. Valve internal components
are field replaceable and they are the same
components used in the Sherwood GV
series, which has a proven track record in
industrial gas service.
Assembly M25-16169A & 16169A-1

1. Apply 3 dabs of lubricant around the perimeter of the lower
plug threads, approximating the size of a pencil eraser for
each. Locate lubricant toward the lower most threads clos-est to the crimped seat but using care not to get lubricant on
the nylon seat. Use Braycote 803 lubricant.
2. Being careful not to damage the bonnet sealing surface in
the valve body, install the new lower plug into the cham-
ber, seat first and tighten using a square drive until it is fully
seated.
3. Engage the new bonnet and stem subassembly into the
valve body and hand tighten by turning clockwise. Rotate
stem square until it becomes engaged in the lower plug.
4. Using an 11/16" hex socket and torque wrench, tighten the
bonnet to 50-60 ft. lbs. NOTE: A properly calibrated torquewrench must be used. Over torquing will damage the bon-
net.
5. Place the handwheel over the stem square. Thread the
handwheel nut onto the stem thread and tighten to 15-35
in. lbs.
6. To ensure free and smooth operation, open and close the
valve several times by turning the handwheel.
