3M PPS 2.0 Pressure Cup Kit for Accuspray HGP, Midi 13.5 oz — Pressurized Feed for High‑Viscosity Coatings

The 3M PPS 2.0 H/O pressure cup (26121, Midi 13.5 oz) is a pressurized paint cup kit—pressure cup, collar and air hose—designed to deliver thick, high‑viscosity coatings cleanly and consistently when used with the 3M Accuspray HGP spray gun.

This pressurized cup system collapses a single-use liner using air routed through the included hose so heavy materials are forced to the gun without siphoning or gravity feed. It replaces multi-cup mixing and filtering steps, reduces cleaning, and helps minimize overspray by keeping material under controlled pressure. The Midi 13.5-ounce size balances capacity and portability for medium-length jobs where high-build primers, adhesives, bedliners or sound-damping coatings are required.

How does the pressure cup make spraying high‑viscosity materials easier?

The included hose channels compressed air into the collar to collapse the liner and actively push thick fluids into the spray gun. That positive pressure feed prevents clogging and maintains a steady flow, so coatings designed to build thickness apply smoothly without repeated thinning.

• Air-driven liner collapse for continuous material feed
• Works with heavy primers, gelcoats, adhesives and bedliners
• Reduces need to thin or repeatedly stir thick products
• Helps maintain consistent spray pattern and mil build

What components come with part 26121 and how do they work together?

The 3M kit includes a durable reusable cup body, a threaded collar that secures a fresh PPS 2.0 liner and a hose that connects to the Accuspray HGP gun’s air source. Together they create a sealed, pressurized reservoir so each batch is kept isolated and contamination risk is reduced.

• Sturdy reusable cup body with pressure release for safety
• Collar accepts PPS 2.0 single‑use liners and lids
• Air hose supplies pressure to collapse liner and move material
• Compatible with 3M Accuspray HGP high-output spray guns

Why choose a PPS pressure cup over traditional metal cup systems?

PPS liners and lids let you mix directly in a disposable bag and swap lids for each batch, cutting contamination and cleanup. The system can lower solvent use and prep/cleanup time compared with aluminum or fixed reservoir setups because you discard the liner rather than scrub a cup interior.

• Single-use liners reduce cross-contamination risk
• Less solvent and less labor for cleaning between color or product changes
• Tighter control of overspray and less wasted material
• Faster turnaround for consecutive jobs or color changes

How much material will the Midi 13.5-ounce cup handle and what projects is it best for?

At 13.5 ounces (Midi size), the cup is sized for medium runs where portability and frequent liner changes are helpful. It’s ideal for automotive details, spot repairs, small furniture finishes, marine touch-ups and application of bedliner patches or sound-damping spots.

• Midi capacity balances job length and weight for hand-held spraying
• Good for auto body spot repairs and localized undercoating
• Suitable for marine gelcoats and furniture refinishing tasks
• Convenient for projects requiring frequent material swaps

Who is this for: the 3M PPS 2.0 H/O pressure cup 26121 is aimed at professional refinishers, fleet maintenance technicians, marine and industrial applicators, and advanced DIYers using the 3M Accuspray HGP gun. It suits users who need an efficient way to apply high‑build or viscous materials while cutting cleanup time, solvent use and contamination risk.
