In Endura finish and anodized blue/red or black, these fittings swivel 360° to maximize hose installation for quick alignment of ends after hose assembly. The 120°, 150°, and 180° sizes have a standard or tight radius. For cramped spaces, a tight radius fitting provides a shorter distance between fittings. The Endura finish offers the protection of stainless steel but the weight of aluminum. It won't corrode on alcohol and marine applications and lasts up to 5x longer than aluminum and 10x longer than cad-plated steel. Sold each.
