Straight-Bore Nozzle

The F113-029 uses a straight-bore nozzle, producing a concentrated abrasive stream.

This configuration is useful for aggressive cleaning, coating removal, and surface preparation where a focused blast pattern is preferred.

Combined with its large 1/2" bore, the F113-029 is intended for applications where substantial blasting capacity is required.

Why Boron Carbide?

Boron carbide is one of the most wear-resistant materials commonly used for abrasive blast nozzles.

Compared with ceramic and tungsten carbide, boron carbide is particularly attractive for demanding production applications where nozzle wear and downtime are important considerations.

It's well suited for:

• Production blast cabinets
• Frequent or continuous blasting
• Industrial surface preparation
• Aggressive abrasive applications
• High-use blasting operations
• Applications where extended nozzle service life is important

Actual service life depends heavily on abrasive type, media size, operating pressure, and blasting conditions.

How a Suction Blast Gun Works

Compressed air passes through the 1/4" air jet, creating the low-pressure area necessary to draw abrasive media through the media hose and into the mixing chamber.

The abrasive combines with the compressed-air stream and is accelerated through the 1/2" boron carbide straight-bore nozzle toward the work surface.

Correct matching of the nozzle and air jet is important for proper abrasive pickup and efficient blast-gun performance.

Air Consumption / Compressor Requirements

CFM figures are provided as a general siphon-blast compressor-sizing reference. Actual air consumption can vary with gun configuration, nozzle condition, operating conditions, and the compressed-air system. The compressor must be capable of delivering the required CFM at the desired operating pressure.

Applications:

• Production suction blast cabinets
• High-capacity abrasive blasting
• Industrial surface preparation
• Paint and coating removal
• Rust and corrosion removal
• Cleaning fabricated and machined components
• Equipment restoration
• Manufacturing operations
• Industrial maintenance
• Larger workpieces and surface areas

Checking Nozzle Wear

Boron carbide offers exceptional wear resistance, but the nozzle should still be periodically inspected.

As the nozzle bore enlarges, compressed-air demand increases and blast performance can change.

Watch for:

• Enlarged or irregular nozzle bore
• Increased compressed-air consumption
• Changes in blast pattern
• Reduced abrasive velocity
• Reduced blasting efficiency
• Increased abrasive consumption
• Difficulty maintaining operating pressure

Periodically measuring the nozzle bore helps identify excessive wear before it significantly affects performance.

Finding Parts for Older Universal / Uniblast Equipment

Universal Equipment Manufacturing and Uniblast Technologies blasting equipment has been used in industrial applications for many years, and parts for older machines can sometimes be difficult to identify.

That's why we include the original manufacturer part number and complete nozzle/air-jet configuration whenever possible.

For this assembly, the key identification information is:

Universal / Uniblast F113-029 – 1/2" Boron Carbide Straight-Bore Nozzle with 1/4" Air Jet

Important:

This listing is for one Universal Equipment Manufacturing / Uniblast Technologies F113-029 complete blast gun assembly with 1/2" boron carbide straight-bore nozzle and 1/4" air jet.

Always verify the F113-029 part number, 1/2" nozzle bore, straight-bore configuration, and 1/4" air-jet size before ordering.

Completely shut off and relieve compressed-air pressure before installing, removing, or servicing any blast gun, nozzle, air jet, hose, or related blasting component. Never operate abrasive blasting equipment with damaged or improperly secured components.
