Coilhose Pneumatics ST11 Safety Booster Nozzle 1/8 Npsm

Product Description

The COILHOSE PNEUMATICS ST11 is a safety booster nozzle designed for use with 1/8-inch tip blow guns in compressed-air applications. It threads onto compatible blow guns via a 1/8 NPSM connection and is built to meet OSHA dead-end pressure requirements, making it the correct choice for industrial and shop environments where air blow-off safety compliance is mandatory. At 1.5 inches in length, the nozzle is compact and adds minimal profile to the blow gun assembly. HVAC technicians, maintenance mechanics, and shop personnel use this type of nozzle to stay within OSHA-regulated air pressure limits during parts cleaning and drying tasks.

This nozzle is suited for light industrial, commercial, and shop maintenance environments where blow guns are used for debris removal, drying, and general air-blowing tasks. It is a direct replacement or add-on accessory for blow guns with 1/8-inch tips. The booster design allows adequate airflow while limiting dead-end static pressure to OSHA-compliant levels, reducing risk of injury from accidental contact with skin or eyes.

Key Features

• OSHA-compliant safety booster nozzle design limits dead-end pressure during blow-off operations
• 1/8 NPSM thread for secure, leak-resistant attachment to compatible blow guns
• Compact 1.5-inch length keeps the blow gun assembly maneuverable
• Compatible with 1/8-inch tip blow guns for straightforward retrofit or replacement
• Lightweight at 0.5 pounds for reduced hand fatigue during extended use

Compatibility

Designed for use with 1/8-inch tip blow guns using a 1/8 NPSM thread connection. Refer to the blow gun manufacturer specifications to confirm thread compatibility before installation.

Installation Notes

Installation is performed by maintenance technicians or shop personnel familiar with compressed-air tool accessories. Always depressurize the air line and disconnect the blow gun from the air supply before attaching or removing the nozzle. Thread the nozzle onto the blow gun tip by hand first, then snug with an appropriate wrench — do not overtighten, as NPSM threads are straight and rely on a sealing surface rather than taper. Verify the connection is secure and leak-free before returning the tool to service.
