Hose End #4 Straight

The Hose End #4 Straight is a precision hydraulic fitting engineered for marine fuel and coolant line applications where reliability under pressure cannot be compromised. Built by A-1 PRODUCTS, this 4 AN straight connector serves as the backbone of secure hose-to-fitting assemblies on boats, whether you're managing fuel delivery systems, cooling loops, or pressurized fluid transfer. Anglers and boaters who demand leak-free performance in saltwater and freshwater environments choose this fitting for its direct, no-compromise design.

Manufactured from aluminum and finished in durable blue and red anodizing, the Hose End #4 Straight connects 4 AN hose to 4 AN female ports with a proven straight configuration that eliminates kinks and flow restriction common in angled fittings. The anodized aluminum construction resists corrosion in harsh marine environments while maintaining lightweight integrity—critical when every ounce matters on a fishing vessel or performance boat. This straight design is the industry standard for fuel and hydraulic systems where direct-path pressure delivery ensures consistent system response and eliminates turbulence-induced wear.

This fitting is ideal for boaters upgrading or repairing fuel delivery, cooling, and hydraulic systems on modern recreational and commercial vessels. Installation requires standard hose crimping equipment compatible with 4 AN fittings, and the compact 2.9 x 0.65 x 4.65-inch profile fits tight engine bays and bilge spaces without modification. Use this connector wherever your 4 AN hose routing demands a straight, no-elbow solution—from high-performance outboard installations to inboard fuel systems and trim/tilt hydraulics.
