About this item

  • CONVENIENT INFLATION: This presta valve adapter can convert your presta valve into schrader, so you can inflate your tire with a standard schrader pump or car air compressor. Much cheaper and less wasteful than buying a new tube!
  • EASY TO INSTALL: Just loosen the tip of the presta valve to a suitable place and screw on the presta valve adapter, then connect to a schrader pump or air compressor to inflate.
  • DURABLE CONSTRUCTION: Manufactured with high-quality solid brass, which is more durable and stronger than alloy aluminum. The built-in o-ring rubber seal protects against air leakage. The precision machined threads ensure a longlasting and secure connection.
  • ALWAYS BE PREPARED: This compact and light presta valve adaptor can be stored in your riding bag or jersey while you ride, or left on the tire. So you are always prepared to inflate anywhere and anytime. Keep your bike rolling!
  • VERSATILE: These valve stem adapters are suitable for mountain bikes, electric bikes and more.

Nice to have some sturdy adapters since most compressor air hoses want to are oriented toward Shrader valves.

A simple adapter but the machining quality and finish is excellent.I have tested it using my high precision pressure gauge and consistently I was only loosing 0.1 psi every time it got disconnected from the tire valve. This a little as you can loose from a standard valve connector without using specialized and expensive "zero loss" valve connector.

Good quality construction and material. I like how I can now use my cordless air pump on my street bike.

Bought some of these locally without the rubber gasket by threads and leaky when connect. These solved it by having a positive fit. No more pfffft!

I have a garden cart that that my Mom bought 40+ yrs ago. When I was clearing out the shed I saw the old cart with its 2 huge bike style wheels of course the tires were flat and wouldn't hold air I figured it would be great to use to haul out the old junk in the shed and across a large yard to my truck. Well got new inner tubes on Amazon they arrived and got them on the rims only to find the valves are the newer tiny type and all the air pumps and compressor I have only fit that old standard valve. Amazon to the rescue again the adaptors came next day 4 in a pack ( so I put taped 1 on all the pumps ) works great super inexpensive and really heavy well made brass fitting.
