Earl's Performance Pro-Lite 350 Braided Nylon AN Hose

The Earl's Performance Pro-Lite 350 is a lightweight, high-pressure AN hose line engineered for serious racing and high-performance street applications. Constructed in the USA, the Pro-Lite 350 delivers the industry's highest pressure rating in a rubber-lined, nylon-covered hose design — combining superior durability with meaningful weight savings over traditional stainless steel braided hose alternatives. Earl's Performance Plumbing has been bringing aviation-grade fluid transfer technology to the automotive performance market for over five decades, and the Pro-Lite 350 carries on that legacy with a construction trusted by professional builders and race teams worldwide.

Advanced Three-Layer Construction:

• Abrasion-resistant nylon outer sheathing bonded to a textile inner braid forms a tough, integrated shell that stands up to routing wear and underhood abrasion
• Textile inner braid embedded in a synthetic rubber liner delivers exceptional burst strength, pressure retention, and delamination resistance
• Integrated construction maintains hose integrity through heat cycling, vibration, and tight-radius routing demands

Proven Performance Ratings:

• 350 PSI maximum working pressure — the highest pressure rating available in a lightweight rubber-lined hose design
• Operating temperature range of -40°F to +300°F for reliable performance across extreme environments
• High vacuum resistance maintains integrity under negative pressure and suction conditions
• Hot oil temperature capability makes it suitable for demanding lubrication and cooling circuit applications

Lightweight Advantage:

• Significantly lighter than traditional stainless steel braided hose — replacing a full plumbing system with Pro-Lite 350 delivers real weight savings across the entire build
• Well-suited for oval track, drag racing, road racing, and high-performance street builds where weight reduction matters

Shop- and Track-Friendly Design:

• Easy to cut and assemble in the shop or at the track — no special tooling required
• Excellent flexibility simplifies routing through tight engine bays and chassis tunnels
• Available in a full range of AN sizes and lengths to suit virtually any plumbing application

Important — Hose End Compatibility:

Pro-Lite 350 hose is specifically engineered for use with Earl's Swivel-Seal, Auto-Fit, and Auto-Crimp hose ends exclusively. Use of other manufacturers' hose ends is not recommended and may compromise pressure capability and service life. An inner support spring is recommended for suction line applications or unusually tight bend radii.
