The Graco RAC X One Seal prevents paint leakage between the gun, tip, and tip guard — the weak point where most airless spray failures occur. For Montana contractors dealing with temperature extremes that stress equipment seals, this gasket maintains the critical barrier that keeps paint flowing through the tip instead of bleeding around it.
The 5-pack of model 246453 gaskets works exclusively with RAC X SwitchTips and Guards, making them essential maintenance inventory for any contractor running Graco’s professional spray systems. At 2.65” W x 0.7” H package dimensions, they store easily in a toolbox or spray rig.
Performance and Material Compatibility
The seal handles water-based materials, latex coatings, oil-based coatings, and solvent-based coatings — essentially everything a painting contractor sprays. Made from plastic, metal, rubber, and elastomer materials, the multi-material construction provides chemical resistance across the coating spectrum while maintaining flexibility in cold weather.
Professional contractors value these gaskets for maintaining consistent spray quality and their tool-free installation. Worn seals cause uneven spray patterns — the telltale sign that wastes material and forces callbacks for touch-ups.
The critical maintenance rule: replace the seal every time the spray tip is replaced. Skip this step and even a new tip won’t spray properly. The old seal takes a compression set from the previous tip and won’t mate correctly with the new one.
Installation and Compatibility Specifics
Installation happens without tools — the gasket seats directly into position. No wrenches, no special fixtures. The design works specifically for RAC X SwitchTips, RAC X Guards, and RAC X FF LP (Fine Finish Low Pressure) SwitchTips.
Professional painting projects where maintaining consistent spray patterns and preventing leaks are critical benefit most from fresh seals, especially when working with various materials and spray tips. A worn seal costs more in wasted material and rework time than the replacement gasket.

Verdict
Worth it for any contractor running RAC X equipment. Perfect 5-star ratings across Amazon, Lowe’s, Ring’s End, and Painters Solutions confirm what experienced spray operators know — proper seals prevent the paint waste and pattern problems that eat into profit margins.
The 5-pack quantity hits the sweet spot for maintenance inventory. Keep one pack in the spray rig, another in the shop. Montana’s temperature swings from -30°F winters to 100°F summer days stress all rubber components harder than milder climates. Fresh seals are cheap insurance against mid-job failures.
Common concerns with such gaskets include wear over time, especially when spraying abrasive materials. Deck stains with anti-slip additives and elastomeric coatings chew through seals faster than standard latex. Check seal condition after spraying abrasive materials.
For contractors maintaining multiple RAC X guns, buying these gaskets by the case makes sense. The tool-free changeout means swapping seals between color changes or at the first sign of leakage pattern. At Western Building Center’s paint departments from Kalispell to Great Falls, these maintenance basics keep professional spray rigs running season after season.
Frequently Asked Questions
Q: How often should I replace Graco RAC X One Seal gaskets?
Replace the Graco 246453 seal every time you replace the spray tip — this ensures proper mating between the new tip and seal. Worn seals cause uneven spray patterns and paint leakage between the gun, tip, and tip guard.
Q: What materials can I spray with the RAC X One Seal gaskets?
The Graco RAC X One Seal handles water-based materials, latex coatings, oil-based coatings, and solvent-based coatings. The plastic, metal, rubber, and elastomer construction provides chemical resistance across the full spectrum of professional coatings.
Q: Do I need tools to install these Graco tip gaskets?
No tools required — the Graco 246453 gaskets install by hand, seating directly into position between the gun and tip. This tool-free design speeds up maintenance and tip changes on the jobsite.
Q: Will these gaskets work with my older Graco spray tips?
The model 246453 gaskets work exclusively with RAC X SwitchTips, RAC X Guards, and RAC X FF LP (Fine Finish Low Pressure) SwitchTips. They won’t seal properly with non-RAC X equipment.
Q: How many gaskets come in the Graco 246453 pack?
Each pack contains 5 gaskets measuring 2.65” W x 0.7” H in package dimensions. The 5-pack quantity provides enough spares for multiple tip changes or to keep backup inventory in your spray rig.
