3M PPS 2.0 Adapter S43 for Iwata & AirGunsa 1/4" BSP — Stainless Steel, Solvent‑Resistant, Wide‑Base Lid

3M PPS 2.0 Adapter #S43 (26139) is a stainless-steel adapter that lets you mount Iwata and AirGunsa gravity side‑mount guns to the PPS 2.0 disposable-lid spray cup system for faster cleanup and less waste.

The 3M PPS 2.0 Adapter S43 provides a robust, solvent-resistant connection between selected Iwata/AirGunsa spray guns and the PPS 2.0 cup system. Built from stainless steel with a wide-base lid interface and four-point contact, this adapter preserves spray stability while enabling the single-use lid-and-liner convenience of PPS 2.0. Use it to keep your preferred gun — such as the Iwata Supernova or AZ3 HTE series — while gaining the faster mixing, filtering and cleanup benefits of the PPS 2.0 platform.

Which spray guns are compatible with this adapter?

The S43 adapter is designed specifically for certain Iwata and AirGunsa gravity side-mount models that accept a 1/4" male, 19 thread BSP fitting. It mates the gun inlet to the PPS 2.0 lid so you can attach standard PPS cups and liners without modifying the gun.

• Compatible models: Iwata Supernova LS-400, Supernova WS-400, Iwata AZ3 HTE 2 and AirGunsa AZ3 HTE 2.
• Thread spec: 1/4" male, 19 thread BSP.
• Designed for gravity side-mount guns with matching inlet threads.

How does the adapter improve cleaning and prep time?

By using PPS 2.0 disposable lids and liners, you avoid transferring mixed paint between cups and reduce the need for extensive solvent washes. The adapter’s wide bowl and stable lid connection speed up removal and replacement of lids and liners, slashing cleanup tasks.

• Wide bowl design makes flushing and wiping quicker.
• Single-use liners eliminate cross-contamination between color changes.
• Reportedly reduces prep and cleanup time by up to 50% versus conventional metal-cup systems.

Is the S43 durable and solvent-resistant for industrial use?

Yes — the adapter is machined from stainless steel to withstand common paint solvents and repeated use in industrial environments. Its solid construction and four-point lid connection deliver secure, repeatable performance under shop conditions.

• Stainless-steel body resists corrosion and solvent attack.
• Four contact points between lid and gun increase stability and reduce wobble.
• Suitable for applications that use primers, basecoats, clears, gelcoats, and sprayable adhesives.

Will using this adapter change how I mix or filter materials?

The adapter itself doesn’t alter mixing ratios or filtration, but it enables the PPS 2.0 system’s built-in mixing marks and single-use filtering features. You get printed universal mix ratios on PPS cups and simple visual access to fluid level through the cup’s window.

• PPS cups include printed mix ratios for accurate batching.
• Disposable liners provide integrated filtering and clean swaps between colors.
• Clear access window on PPS cups helps check viscosity and volume without removing the lid.

Who is this for? The 3M PPS 2.0 Adapter S43 (26139) is aimed at professional refinishers, collision repair shops, industrial painters and serious hobbyists who use compatible Iwata/AirGunsa gravity guns but want the faster changeovers, reduced solvent use and lower contamination risk of the PPS 2.0 system. It’s an industrial‑grade accessory — intended for occupational or professional use where solvent resistance and dependable connections are required.
