Fitting Replacement Oliv e for PTFE Hose Ends -10

The Fitting Replacement Olive for PTFE Hose Ends -10 by Vibrant Performance is a critical compression fitting component designed for high-performance fuel, oil, and coolant line systems in modified and racing vehicles. This olive—also called a ferrule or seal ring—creates a leak-proof seal when compressed between the hose barb and the fitting body, making it essential for anyone rebuilding fuel injection systems, custom cooling loops, or upgrading to braided PTFE lines. Whether you're refreshing an aging fuel system on a street machine or assembling a competition engine bay, replacement olives ensure your hose connections remain airtight under pressure and vibration.

Manufactured to Vibrant Performance's strict tolerances, the -10 olive is engineered to work exclusively with -10 AN (JIC equivalent) PTFE hose ends and barbed fittings. The olive's conical geometry distributes clamping force evenly across the hose inner diameter, preventing extrusion and pinching that can lead to rupture under boost or high-flow conditions. Vibrant's engineering ensures compatibility with PTFE-lined hose (fluoropolymer core with braided nylon or stainless outer), which resists fuel permeation, thermal expansion, and chemical degradation far better than rubber alternatives—critical for fuel-injected engines running E85, methanol, or aggressive fuel blends.

Mechanics and tuners rebuilding fuel rails, intake systems, or custom coolant circuits will appreciate having spare olives on hand; compression fittings are reusable, but the olive itself should be replaced each time you disconnect and reconnect a hose to maintain seal integrity. The -10 size mates with standard -10 AN hose barbs found on fuel pumps, fuel pressure regulators, and custom manifold work. Installation requires no special tools—hand-tightening followed by a wrench turn ensures proper compression without over-torquing and damaging the fitting.
