Berg braided stainless steel covering "lifetime PTFE" hose with swedged AN fitting female ends. This 1000 PSA, heat resistant type hose is slightly more expensive than others, however is the only hose you should ever need, making it far more economical. A lifetime investment. (I installed mine in 1969 and they are still on my engine today).
1. PTFE hose resists temperature deterioration for years. Outlasts cheaper stainless covered neoprene hose over 10 to 1.
2. Swedged ends are capable of withstanding to 1000 PSI. I have seen screw together type hose ends come apart under 8 pounds of fuel pump pressure at the carburetor and burn the car to the ground. I have even seen some fall apart from road vibration. Do not gamble, get genuine Gene Berg hoses.
3. PTFE hose with braided stainless steel covering protects against damage occurring from abuse like rocks, etc.
4. PTFE hose has a far higher flow rate due to its slipperiness. Furthermore, it will maintain this same flow over the years, as it will not swell shut like neoprene or rubber hose often do after a few years of use. Made in the USA. SW 2#
Note: We measure the length of the hose from the tapered seat to the tapered seat. For example: Our 12" hose actually has only 11" of hose as you gain 1/2 inch of length on each end due to the fitting. Keep this in mind when ordering custom hoses.
