3M PPS 2.0 Adapter S15 3/8 in Male 19 BSP — Stainless Steel, Wide-Base Four-Point

The S15 adapter from 3M expands the PPS 2.0 system’s compatibility so you can keep using your preferred spray gun while taking advantage of PPS disposable lids and liners. Built from stainless steel with a wide base and a four-point connection, this adapter provides a secure interface between the gun and the PPS cup lid. It’s intended for industrial and occupational use where durability, solvent resistance, and quick cleanup matter.

Which spray guns does the S15 adapter fit?

The S15 is designed as a 3/8" male, 19-thread BSP adapter to match several common professional spray guns. Use the model chart provided by 3M or the seller images to confirm your gun’s adapter number before purchasing. If your gun appears on the compatibility chart as the matching model, the S15 will allow direct attachment to PPS 2.0 lids.

• Thread type: 3/8" male, 19 BSP — matches specific gun inlet threads
• Check 3M compatibility chart to confirm your gun model
• Adapter enables direct gun-to-lid connection without modifying the gun

How does this adapter improve cleanup and workflow?

Pairing your spray gun with PPS 2.0 via the S15 adapter reduces paint waste and cuts cleaning time by removing the need for extra mixing cups and transfers. Each spray uses a fresh lid and liner, so you discard used consumables rather than flushing paint through metal cups. That lowers solvent consumption and reduces the risk of contamination between jobs.

• Use disposable lids and liners to avoid mixing in extra cups
• Less solvent needed—up to significant reductions versus traditional metal cups
• Faster turnaround: fewer parts to clean, quicker job changeovers

What are the construction and performance benefits of the S15 adapter?

The S15 is machined from stainless steel for long-lasting, solvent-resistant performance in industrial environments. Its wide bowl design and four-point lid connection give a firm, stable interface between gun and lid, improving handling and reducing leak or wobble risks. The robust build helps maintain consistent spray performance across multiple shifts.

• Stainless steel construction resists solvents and mechanical wear
• Wide base and four-point contact for improved stability
• Easy-to-clean shape—large access area for swift maintenance

Can the S15 adapter handle different coatings and applications?

Yes. When attached to the PPS 2.0 system, the S15 supports a broad range of sprayable materials used in automotive, marine, industrial, and specialty finishing. While the adapter itself is a mechanical fitting, using PPS lids and liners allows safer handling of paints, primers, clearcoats, varnishes, adhesives, and other sprayable media.

• Compatible with paints, primers, sealers, clears, varnishes, gelcoats, and adhesives
• Supports industrial finishing workflows across vehicles, equipment, furniture, and more
• Designed for occupational use in professional settings

Who is this for: The 3M PPS 2.0 Adapter S15 (26046) is aimed at professional painters, body shop technicians, refinishers, and industrial finishing teams who want to retain their current spray guns while adopting the faster, cleaner PPS disposable lid and liner workflow. If you need a solvent-resistant, solid gun-to-lid connection to speed prep and cleanup without changing gun hardware, the S15 is a practical component for professional use.
