The Texas Speed 10AN Stainless Steel Braided PTFE Hose is a 10 foot length of flexible 10AN hose with a PTFE inner liner and a stainless steel braid outer cover. The PTFE liner is the key feature: it does not allow fuel vapor to permeate through the hose wall, which is why PTFE-lined hose is the usual choice for gasoline and E85 fuel systems where a rubber-core hose would eventually let fuel smell escape. In this size, -10AN is a larger size commonly used for oil cooler lines, remote oil filter lines, large fuel feed lines and coolant plumbing.
Texas Speed rates its PTFE flex hose for fuel, water, oil, transmission fluid and air, and builds it to handle demanding conditions with protection against abrasion and corrosion across all weather conditions. The stainless steel braided cover protects the liner from chafing where the hose crosses brackets or frame rails. This listing is for a single 10 foot length; Texas Speed offers the same hose in other lengths and diameters, and PTFE-lined hose should be assembled with hose ends made for PTFE hose, such as the Texas Speed PTFE swivel hose ends sold in the same AN size.

FAQ
What is the Texas Speed 10AN stainless steel braided PTFE hose used for?
This 10 foot length of 10AN PTFE-lined hose is rated by Texas Speed for fuel, water, oil, transmission fluid and air. In the 10AN size it is commonly used for oil cooler lines, remote oil filter lines, large fuel feed lines and coolant plumbing.
Is this 10AN PTFE hose safe for E85 and gasoline?
Yes. The Texas Speed 10AN stainless steel braided hose uses a PTFE liner, which Texas Speed states eliminates fuel vapor permeation. PTFE is the lining normally chosen for gasoline and E85 fuel lines because it does not let fuel vapor pass through the hose wall.
What hose ends work with Texas Speed 10AN PTFE hose?
PTFE-lined hose requires hose ends designed for PTFE hose, which use an internal ferrule or olive to seal on the liner. Texas Speed offers 10AN straight and angled swivel PTFE hose ends in black 6061 aluminum that are made to work with its PTFE braided hose. Standard rubber-hose AN ends should not be used.
How long is this hose and does Texas Speed sell other lengths?
This listing is a single 10 foot length of 10AN stainless steel braided PTFE hose, Texas Speed part 25-10003. Texas Speed sells the same hose in several other lengths and in other AN diameters, so choose the length that covers the run with some slack for routing.
Is the Texas Speed 10AN PTFE hose a universal part?
Yes. It is not vehicle specific. The 10AN stainless steel braided PTFE hose can be cut to length and used on any fuel, oil, coolant, transmission cooler or air line that uses -10AN PTFE hose ends.
What is the difference between the stainless steel braided and nylon braided Texas Speed PTFE hose?
Both versions use the same PTFE liner and are rated for the same fluids. The difference is the outer cover. Texas Speed offers its PTFE flex hose with either a nylon braided cover or a stainless steel braided cover, both intended to protect the hose from abrasion and corrosion. This listing is the stainless steel braided version in 10AN, 10 ft.
