i found these on ebay for 11.79 with free shipping.( with a make an offer )
these are alot cheaper than buying the 21 inch long 1/4inch stainless braided hose from other places for 30+ bucks. . the only thing is that it doesn't come with a check valve.

from what i can gather. these hoses are made with the same materials that other air compressors use.(air zenith.etc).somebody correct me if im wrong.

i bought one to use as the leader hose on my york compressor...

that link is just saying item no longer available. whats the psi rating on that ? did it by chance say ? how bout heat resistance ? just curious. my noma fully done in braided stainless with swivels on each end and my god is it not only expensive its certainly near bulletproof. haha

i fixed the link.

it doesn't say the psi rating. but from what ive read. it should be around 450psi. at least that is what i found other ptfe stainless hoses to be rated at.
