Holley has announced the release of the UltraPro series of hose and fittings from Earl’s Performance Plumbing.
Earl’s UltraPro Series hose ends are designed to stand up to the same harsh environments, brutal vibrations, flow requirements and extreme pressures as the UltraPro Series hose. According to the company, the internal seals are a fluoroelastomer material which is resistant to all known fuel, oil and coolants. Bends use a bent tube design for strength and flow, regardless of the severity of the angle. The hose ends are furnace-brazed for a permanent and robust bond. They are assembled with an olive that threads onto the double-helix ribbed inner liner of the hose for positive engagement and retention of the hose ends. High-stress components are made of high strength 2024-T8 grade aluminum. The design of the nuts, sockets and swivels has been optimized for maximum weight savings. They also feature Earl’s popular ANO-TUFF black hard-coat anodizing that actually penetrates the aluminum for a durable and corrosion-resistant shield. Dynamic Swivel technology is used in selected hose ends which allows 360° of rotation after installation. They are available in both twist-on and crimp-on styles for more plumbing options. SAE port, jump size and Wiggins connector adapters are also available.
