90° and 135° Metal Valve Stem Extensions – Inflate any tyre, no matter how awkward the valve position
Ever struggled to inflate a tyre because the rim, brake disc, or hubcap makes the valve impossible to reach? We’ve all been there, stuck on the side of the road with low pressure and no way to connect the pump. This set of 4 copper valve extensions is the perfect solution, featuring two 90° and two 135° angles to handle any tight space.
Note: This set includes 4 pieces in total — 2 x 90° extensions and 2 x 135° extensions. Compatible exclusively with Schrader valves (standard car/bike valves).
Why choose this set? (Key Benefits):
- Two angles in one set — 90° for completely obstructed valves and 135° for partially restricted access; you’ll always have the right tool for the job.
- Integrated valve with sealing ring — Maintains tyre pressure during installation and removal, ensuring zero air loss.
- Precision-machined copper — Far more durable than zinc or plastic alternatives; won’t rust or corrode even after months of use in damp conditions.
- Universal pump compatibility — Works with any standard manual pump, foot pump, or electric compressor with a Schrader connection, including digital pressure gauges.
- Compact design — At 40mm long and weighing just 13g each, they fit easily into your glovebox, bike bag, or emergency kit.
- Tool-free installation — Simply screw them onto your existing valve in under 30 seconds; no need to remove the wheel.
Performance and Build Quality
Each extension is crafted from high-grade, corrosion-resistant copper. Unlike cast or plated alternatives, our precision-machined finish ensures superior resistance to wear, moisture, and temperature fluctuations. They won’t crack under pressure or leave unsightly oxidation marks on your rims.
The internal sealing ring engages automatically upon tightening, locking the air inside the tyre and allowing you to connect your pump without any pressure drop. With a 10mm diameter and standard Schrader threading, they are compatible with virtually every pump or pressure gauge on the market.

Frequently Asked Questions
Are these compatible with all valve types?
They are designed exclusively for Schrader valves — the standard type found on cars, SUVs, trucks, most bicycles, and electric scooters. They are not compatible with Presta valves (commonly found on high-performance road bikes).
Will air leak out when I install the extension?
No. The integrated valve and internal sealing ring lock the air in the moment you screw them on. Tyre pressure remains constant, so you won’t lose any air during installation or removal.
Can I leave these on permanently?
Yes. The copper construction is rust-proof, and the valve maintains a reliable seal long-term. We recommend a quick check of the connection after extreme weather conditions, such as heavy frost or intense heat.
Which angle do I need — 90° or 135°?
If the valve is completely inaccessible from the front, use the 90° extension. If you have a little more space but a direct connection is still difficult, the 135° angle provides a smoother, more ergonomic orientation. We include both types so you are prepared for any wheel configuration.
