3M PPS 2.0 Pressure Cup for Accuspray HGP, Midi 13.5 oz — Air Hose & Collar, Reusable Cup

The 3M PPS 2.0 H/O Pressure Cup with collar and air hose (26121, Midi 13.5 oz) is a pressurized paint cup assembly built to deliver thick, high‑viscosity coatings through the 3M Accuspray HGP spray gun for faster, cleaner spraying.

This pressure cup system uses a disposable liner and a reusable cup and collar to collapse material under air pressure, forcing viscous coatings through the gun without the extra filtering and transfers required by metal cup setups. It’s engineered for trade and industrial users who need consistent mil build, reduced overspray and lower cleaning time when applying products like undercoats, bed liners, adhesives, sound‑damping coatings, high‑build primers and gelcoats.

How does the pressure cup help when spraying thick materials?

The included air hose routes compressed air into the collar to uniformly collapse the liner, pushing viscous liquids into the gun without cavitation or intermittent feed. This controlled feed encourages a consistent atomization and spray pattern even with high‑solids formulations.

• Air-driven liner collapse maintains steady material flow.
• Reduces the need to thin aggressive coatings.
• Helps avoid clogs and sputtering during long runs.

What efficiency gains can I expect compared with conventional metal cups?

PPS 2.0 eliminates many handling steps: mix in the liner, snap on the lid and spray. Because liners and lids are disposable, you avoid transferring material between containers and cut cleaning and prep time substantially.

• One‑step mixing and sealing reduces contamination risk.
• Lower solvent use for cleanup compared with aluminum cups.
• Faster changeovers when switching colors or materials.

Is this compatible with my spray gun and what project sizes fit the Midi 13.5 oz cup?

This pressure cup is intended for use with the 3M Accuspray HGP high‑output spray gun and PPS 2.0 lids and liners. The Midi 13.5 ounce capacity is a middle ground for medium‑sized jobs—large enough for multi‑panel automotive repairs yet compact for spot work and smaller parts.

• Designed to pair with 3M Accuspray HGP guns and PPS 2.0 consumables.
• Midi size ideal for auto panels, furniture pieces, and small equipment runs.
• Reusable cup plus disposable liners for quick swaps onsite.

How does the system affect finish quality and overspray?

By maintaining steady material pressure and consistent feed, the PPS pressure cup helps produce a uniform spray pattern with improved mil build and reduced atomization waste. That means better coverage per pass and less cleanup from overspray.

• Consistent mil thickness achievable with fewer passes.
• Reduced overspray lowers product waste and cleanup time.
• Disposable lids/liners minimize contamination that can mar finishes.

Who is this for: The 3M PPS 2.0 H/O Pressure Cup (26121 Midi 13.5 oz) is aimed at industrial and professional users—collision repair shops, fleet and heavy equipment shops, marine and industrial coating applicators—who run high‑viscosity materials and need faster prep and cleanup, repeatable results, and compatibility with the Accuspray HGP system. Note: intended for industrial/occupational use only, not for consumer sale or use.
