The hose/chuck worked great on my 20 year old Joe Blow Floor pump.
Well, not really great as the adaptor I need would not fit into the pump fitting because the O-ring was too big.
I have an O-ring assortment and for one a little smaller that worked.
Once installed I found that the thru swival shaft shaft on the pump was leaking too, so I replaced those O-rings also.
Inflation brought the cost of the replacement hose up to the cost of the pump when I bought it 20 years ago but I am still happy to get it running/working again.

we got along for several months with another valve head and after my wife gave up on it and it hurt a couple friends I finally bit the bullet and bought this replacement for our old Topeak floor pump. HAPPY
Upgrading my older model pump with a new hose and head has been great! All the advantage of the new model at a small fraction of the price. Installation was quick and easy.
