Universal Uniblast F113-018 #8 Rubberized Air Jet – 1/4" Orifice

Keep your Universal / Uniblast suction blast gun operating properly with the F113-018 #8 Rubberized Air Jet. This air jet has a 1/4" orifice and is stamped #8 for size identification.

Designed for Universal Equipment Manufacturing / Uniblast Technologies suction-feed blast guns, the air jet directs compressed air through the gun to create the suction necessary to draw abrasive media into the blast stream.

Air Jet Size Identification

The #8 marking stamped on this air jet identifies the orifice size. It is not an exploded-diagram item number.

#8 = 1/4" Orifice

Universal / Uniblast air jets in this series use stamped size numbers to identify their air-orifice diameter:

• #4 = 1/8"
• #5 = 5/32"
• #6 = 3/16"
• #8 = 1/4"

Always match the correct air-jet size to the nozzle and blast-gun configuration specified for your equipment.

What the Air Jet Does

The air jet is a critical component of a suction-feed abrasive blast gun.

Compressed air passes through the air-jet orifice at high velocity, creating a low-pressure area inside the gun. This draws abrasive media through the media hose and into the air stream before the mixture exits through the blast nozzle.

The relationship between air-jet size and nozzle bore is important. Installing an incorrect air jet can affect abrasive pickup, air consumption, blast performance, and compressor requirements.

Common Reasons for Replacement:

• Worn or enlarged air-jet orifice
• Damaged air jet
• Poor or inconsistent abrasive pickup
• Reduced blasting performance
• Irregular blast pattern
• Rebuilding an older Universal / Uniblast blast gun
• Restoring a gun to its correct nozzle and air-jet configuration

Compressor Requirements

The 1/4" (#8) air jet is a large air jet and requires substantial compressed-air volume compared with the smaller #4, #5, and #6 sizes.

Actual CFM requirements depend on the nozzle paired with the air jet and the operating pressure. Always make sure the compressor can provide adequate CFM at the desired blasting pressure.

Finding Parts for Older Universal / Uniblast Equipment

Universal Equipment Manufacturing and Uniblast Technologies blast equipment has been in industrial service for many years, and older parts information may identify components by the original part number, stamped size, or A57/B57 designation.

For this component, the key identification information is:

Universal / Uniblast F113-018 – #8 Rubberized Air Jet – 1/4" Orifice – A57 & B57

Important:

This listing is for the Universal Equipment Manufacturing / Uniblast Technologies F113-018 #8 Rubberized Air Jet with 1/4" orifice, including #9 and #11.

The #8 stamped on the air jet indicates its 1/4" orifice size and is not a diagram item number.

Other blast-gun components are sold separately unless specifically stated otherwise.

Always verify the F113-018 part number, #8 identification, 1/4" orifice size, and required blast-gun configuration before ordering.

Completely shut off and relieve compressed-air pressure before servicing any blast gun, nozzle, air jet, hose, or related blasting component.
