Single Stage #3 Valves | Variant 2 "Slim"

These are the Slim-style number 3 valves, most notably seen on older IW inflatables and other vintage single-stage designs.

While similar to standard #3 valves, the Slim variant features a slightly narrower 16 mm inside diameter and a more streamlined build throughout. The cap and tang are slimmer, with minimal rim around the top, giving them a sleeker profile. Like all our single stage valves, they include a flapper at the base to act as a one-way valve — but the base itself has a distinct domed shape, a bit unusual compared to other styles and instantly recognizable once you’ve seen one.

Available in packs of 5, 10, or 15, these are perfect for restorations on classic inflatables — keeping your favorites air-tight without sacrificing authenticity.

No need to dig through donor toys or hunt down rare parts — the Slims are back and ready to breathe new life into your collection.
