Product Description: .117" inside diameter X .211" outside diameter.25' roll. A consistent performer lot after lot, Tygon Fuel and Lubricant Tubing is the most requested fuel and lubricant tubing for a variety of applications -- from small engine fuel lines to coolant transfer. Specifically designed to handle most fuels and industrial lubricants, Tygon Fuel and LubricantTubing resists the swelling and hardening caused by hydrocarbon-based fluids. This significantly reduces the risk of failure due to cracking and leakage. Its minimumextractability safeguards the liquid or vapor being transferred against adulteration.
