By Schulz Valve Adapter SV+DV to AV – Silver

Never be caught out by the wrong valve type again. The By Schulz Valve Adapter converts both Sclaverand (SV / Presta) and Dunlop (DV) valves to Schrader (AV / American) format, letting you use any pump or compressor — at the petrol station, at a workshop, or on the road.

Crafted from anodised aluminium, this adapter is built to last and resists corrosion. The integrated O-ring acts as a loss-prevention seal and ensures an airtight connection every time. When you're not using it on the bike, it doubles as a practical keyring attachment so it's always within reach.

Product Specifications

Frequently Asked Questions (FAQ)

Which valve types does this adapter support?

The By Schulz adapter works with Sclaverand (SV / Presta) and Dunlop (DV) valves, converting them to Schrader (AV / American) format so you can use standard pumps and petrol-station air hoses.

What is the valve key function?

The adapter features a built-in valve key / valve core tool that allows you to tighten or loosen the valve core inserts on both AV (Schrader) and SV (Presta) valves — a handy bonus that saves carrying a separate tool.

What is the O-ring for?

The included O-ring serves two purposes: it creates an airtight seal between the adapter and the valve, and acts as a loss-prevention retainer so the adapter stays in place and isn't easily misplaced.

Is it available in other colours?

Yes — the By Schulz Valve Adapter is available in multiple colours (anodised aluminium finish). This listing is for the Silver variant.

How do I carry the adapter when not in use?

The adapter features a keyring loop, making it easy to attach to your keys, bag, or bike toolkit so it's always on hand when you need it.

What are the dimensions and weight?

The adapter measures approximately 6 × 1.5 × 1.5 cm and weighs around 15 g — small and light enough to go unnoticed until you need it.
