Fits F119-032 Pressure Vessel

This O-ring seat is specifically identified for:

Universal / Uniblast F119-032 – 1.6 Cu. Ft. PDH Pressure Vessel, 60° with SG Ports

The F119-032 complete vessel includes the handway assembly, pop-up components, and O-ring seat. The F119-009 allows the O-ring seat to be serviced individually when the complete pressure vessel does not require replacement.

What the O-Ring Seat Does

The F119-009 is part of the pressure vessel's pop-up sealing system.

When the pressure blast system is activated, the pop-up moves into its sealing position at the vessel filling opening. The urethane seat provides the mating sealing surface needed to close the opening so the vessel can build and maintain operating pressure.

When the vessel is completely depressurized, the pop-up releases from the seat, allowing the vessel to be refilled with abrasive media.

Why the Urethane Seat Matters

The pop-up sealing area operates every time the pressure vessel is cycled.

Repeated contact, abrasive contamination, and normal wear can eventually cause the urethane seat to become cut, distorted, worn, or damaged. Once the sealing surface deteriorates, compressed air may escape around the pop-up instead of allowing the vessel to pressurize normally.

Common Reasons for Replacement:

• Urethane sealing surface is worn
• Cuts, gouges, or other damage
• Seat has become distorted
• Air leaking around the pop-up
• Vessel is slow to pressurize
• Vessel will not maintain pressure
• Pop-up does not seal consistently
• Abrasive has damaged the sealing surface
• Rebuilding or servicing an F119-032 pressure vessel

If the Vessel Won't Seal

If an F119-032 vessel leaks around the filling opening, inspect the entire pop-up sealing system, not just the O-ring seat.

Check for:

• Worn or damaged F119-009 seat
• Damage to the mating pop-up
• Abrasive trapped between sealing surfaces
• Restricted pop-up movement
• Cuts or irregularities in the sealing area
• Corrosion or damage around the vessel opening

Even a new urethane seat may not seal properly if its mating component is damaged or abrasive is preventing the pop-up from seating completely.

Finding Parts for Older Universal / Uniblast Equipment

Universal Equipment Manufacturing and Uniblast Technologies pressure blasting systems can remain in industrial service for many years, making the original part and diagram numbers particularly useful when identifying individual pressure-vessel components.

For this component, the key identification information is:

Universal / Uniblast F119-009 / C640 – Yellow Urethane O-Ring Seat – Fits F119-032 Pressure Vessel – Diagram Item #6

Important:

This listing is for one Universal Equipment Manufacturing / Uniblast Technologies F119-009 / C640 Yellow Urethane O-Ring Seat for the F119-032 pressure vessel, identified as Item #6 in the exploded parts diagram.

Pop-up valves, pressure vessel, handway components, valves, piping, and other parts are sold separately unless specifically stated otherwise.

Always verify the F119-009 part number, yellow urethane configuration, Diagram Item #6, and F119-032 vessel application before ordering.

Pressure Vessel Safety

Completely depressurize, isolate, and verify zero pressure in the vessel before servicing the O-ring seat, pop-up assembly, or any other pressure-vessel component. Never loosen, remove, adjust, or service these components while the vessel is pressurized.

After installation, inspect the complete pop-up sealing system and verify that the vessel seals, pressurizes, and depressurizes correctly before returning the equipment to service.
