Shut-Off Quick-Disconnect Design

The Bullard V15 features a shut-off style quick-disconnect mechanism.

When a compatible male quick-disconnect nipple is removed, the coupler's internal valve closes to interrupt airflow through the fitting.

This design allows convenient connection and disconnection of compatible breathing-air equipment during setup and maintenance.

Important: The shut-off mechanism does not provide an independent breathing-air supply. Disconnecting a supplied-air respirator from its air source can interrupt the wearer's breathing-air supply.

1/4" Industrial Interchange Connection

The V15 is designed to accept a compatible 1/4" industrial interchange male quick-disconnect nipple.

The opposite end features 3/8" male NPT threads for connection to compatible equipment with a matching female pipe thread.

These specifications identify two different connections:

• 1/4" Industrial Interchange: Identifies the quick-disconnect fitting profile.

• 3/8" Male NPT: Identifies the threaded pipe connection size and gender.

Both connection types must match your existing equipment.

Common Applications

• Bullard supplied-air respirator systems

• Industrial abrasive blasting

• Sandblasting helmet breathing-air connections

• Industrial spray painting operations

• Compressed breathing-air hose assemblies

• Breathing-air supply equipment

• Respirator air-line maintenance

When Should the Coupler Be Replaced?

Inspect quick-disconnect couplers regularly and replace components showing signs of:

• Air leakage around the connection

• Damaged or worn locking components

• Difficulty connecting or disconnecting

• Loose or unreliable connections

• Damaged male pipe threads

• Corrosion or physical damage

• Malfunctioning internal shut-off valve

Never modify breathing-air couplers or substitute unapproved pneumatic fittings.

Compatibility Information

Before ordering, verify:

• Original Bullard part number

• Required quick-disconnect profile

• 3/8" female NPT connection on the mating equipment

• Approved respirator and breathing-air hose configuration

• Required operating pressure and airflow

Matching fitting dimensions alone does not establish compatibility with a NIOSH-approved respirator assembly.

Important Breathing-Air Safety Information

This coupler is a connection component only. It does not filter, purify, regulate, or monitor breathing-air quality.

Compressed breathing-air sources must meet applicable respiratory protection requirements, including OSHA 29 CFR 1910.134.

Use only manufacturer-approved breathing-air hoses, fittings, couplers, and other components in the respirator configuration specified by Bullard.

Follow Bullard's requirements for operating pressure, airflow, hose length, and approved component combinations.
