Thiokol Cup Gasket Kit for Spraytech HVLP Maxum II

Part number 0276258 is a cup gasket kit constructed from Thiokol material. This kit includes the precision seals that fit between the fluid cup (or material container) and the spray gun's inlet assembly. These gaskets are critical for preventing leaks and ensuring a vacuum-tight seal, which is necessary for proper fluid pickup and consistent spray performance.

This gasket kit is compatible with the Spraytech HVLP Maxum II spray gun. The Thiokol material is specifically chosen for its superior resistance to a wide range of solvents, lacquers, paints, and chemicals commonly used in finishing. Worn or hardened gaskets can cause air leaks, fluid drips, or poor material feed from the cup. Replacing them with this kit restores a reliable seal.

Service Guidance: Clean the cup threads and gun mating surfaces thoroughly before installing new gaskets. Ensure the gaskets are seated flat and are not twisted or pinched. Hand-tighten the cup firmly; over-tightening can damage the threads or deform the new gaskets.

Gasket function and replacement indicators

Primary function of the gaskets
Fluid Seal Prevents material from leaking out between the cup and gun body.
Air Seal Creates an airtight seal for proper suction and fluid draw from the cup.
Chemical Barrier Thiokol material resists swelling, degradation, and chemical attack from coatings.
Vibration Dampening Helps absorb minor vibrations between the metal cup and gun.
When to replace the cup gaskets
Visible Leaks Material seeps from the cup threads or the cup/gun interface.
Poor Fluid Pickup Gun sputters or struggles to draw material, indicating an air leak.
Hardened/Cracked Gaskets Old gaskets are stiff, brittle, cracked, or have lost their elasticity.
Preventive Maintenance Replacing gaskets periodically or when changing to a different, aggressive material type.

Frequently Asked Questions

It is a cup gasket kit made of Thiokol material for the Spraytech HVLP Maxum II. It contains the replacement seals that fit between the fluid cup and the spray gun to prevent leaks and ensure proper material flow.

Thiokol is a type of polysulfide synthetic rubber. It is renowned for its exceptional resistance to solvents, oils, fuels, and a wide variety of chemicals found in paints, stains, and lacquers. This makes it an ideal material for seals in spray finishing equipment where exposure to aggressive chemicals is constant.

If the leak is originating from the threaded connection where the cup screws onto the gun, then yes, replacing the worn cup gaskets with this kit is the most likely solution. First, ensure the cup itself is not cracked and the threads are clean. The vast majority of cup leaks are due to degraded gaskets.

They are not designed to be reused once removed, as they take a set. Replacement frequency depends on usage and material types. For heavy professional use or when switching to very strong solvents, replace them as part of annual maintenance or at the first sign of leakage or stiffness. For occasional use, inspect them regularly and replace when they lose flexibility.
