Valve stem extensions

Can't you fill tires or check tire pressure with these extensions, don't they bleed tires with them? let me know if i'm doing something wrong

Pros
  • Everything is fine!
Cons
  • Minor problems

Revainrating 4 out of 5

More effort to seal, but the fluidity is good.

I've tried a few air liners on these valve extenders and both took a bit of effort to ensure a good seal, but the airflow was significantly better than the longer Slime brands.

Pros
  • Beautifully Packaged
Cons
  • Lots

Be careful! on Tires & Wheels

Great product, very well made and made of high quality material. Be careful adding valve stem caps, I used the caps and the next day all four tires were flat. The caps press against the ball valve at the end of the shaft and deflate.

Pros
  • Very good value for money
Cons
  • -

Ideal if you have flat inflation valves

I used these to lengthen the short inflation valves on my OZ Racing forged alloy wheels. They're threaded, which allowed me to install aftermarket TMPS sensors, and are nice and short to keep the monitors from sticking out too much.

Pros
  • (set of FOUR caps) Muzzy's Inflate Through High Pressure valve stem caps
Cons
  • So far so good

You can't trust the air pressure. They show random pressure every time.

Bought in September but never checked air pressure until February, shows low pressure on all double test caps shows low pressure. After removing the cover, the air pressure is normal. I can't trust them to provide proper air pressure now.

Pros
  • Made in the USA! Typically used on commercial vehicles, RVs, trailers and semi-trailers, but can be used on anything with a valve stem.
Cons
  • disappears

Reliable choice for valve stem extenders

I liked this product; costs a lot less than having to go back to the shop to install valve stems that are outside of my washers/caps. this. garage like; small short valve stems. good goods; and I like their double seal. Have a built-in seal; as are the valve stems they bolt onto (the ones you have now). So that's a big plus. Only reason for four instead of five stars; They are steel - can be a bit heavy with speed, rotating mass and all. Little problem. Solved my problem 100%; I would buy them…

Pros
  • Replaces any standard valve stem cap, Alligator V2B and Haltec DS-1.
Cons
  • Doubtful

Works perfectly with butt plates

I've used them on both a traditional Schrader valve (typical car and often bike size) and a Presta valve (thin) with a simple Schrader adapter and they work great. Exactly as described. I don't know what a negative comment is about. (If you use a Presta like me, remember to loosen the little ring on the Presta valve that allows you to pump air. Leave it open, then just put the Shrader adapter on top and then put it on the adapter. When then when you want to add air you put on the end of the…

Pros
  • Double high pressure seal inflated through the valve cap, designed for heavy duty and high performance. Measure and fill the valve extensions directly through the cap.
Cons
  • Interchange Availability
