"The most comprehensive source for Automotive Tools & Equipment" Manifolds & Hoses Premium Refrigerant Charging Hoses All Robinair hoses are built for maximum life and dependability. A strong, six-sided crimp provides a reliable connection between the hose and ferrule, even at maximum pressures. Coupler nuts are deeply knurled for quick-finger-tightening. These top quality hoses are available in the industry's widest selection of sizes, lengths and styles - both individually and in color-coded sets. Enviro-guard® Hoses Enviro-Guard® hoses are made of a special composite material which prevents virtually any permeation of refrigerant, yet they remain flexible and easy to work with day after day. All Enviro-Guard® hoses are available with Quick-SealTM fittings which further prevent the release of refrigerant to the atmosphere by automatically sealing when the fitting is disconnected, helping to prevent spray-back and finger burn. Standard Hoses Standard hoses are neoprene-coated to help make them wear-resistant and flexible. Like all Robinair charging hoses, they're designed to withstand working and burst pressures far in excess of normal charging pressures - and they're quality tested for your safety. Long-lasting standard hoses are equipped with standard fittings. A 45 degree bend and valve core depressor on one end make access to A/C systems convenient. Standard hoses are also available with Quick-SealTM fittings. 3/8" Hoses Use these hoses for faster evacuation. Tests prove that larger diameter hoses improve the efficiency of the vacuum pump and reduce pull-down time. Our 3/8" hoses come in yellow and black with standard straight fittings on both ends. Dependable Manifold Gauge Sets Robinair builds manifolds that you can rely on - manifolds which give you accurate readings for testing and charging without guesswork. All Robinair manifolds are designed for easy operation and long life, with quality components and construction. Manifolds are available in a variety of styles and also without hoses so you can put together a set to meet your specific needs. Precision Gauges Precision Gauges are clearly marked for easy reading and accurate measurements. They include: Vibration free dry gauges on all manifolds Durable color-coded cases and rugged Lexan® Lenses Brass 1/8" MPT connection All Robinair gauges are made in the U.S.A. Valve Seats Resilient nylon composition assures a tight seal and long life. Double O-ring seals reduce wear. Designed for full capacity when the valve has been opened three turns. Durable Handwheels Molded of tough Lexan® for long life Color-coded for your convenience Quickly open to full flow QuickTM Seal Fittings Quick Seal fittings automatically seal and prevent refrigerant from discharging when hoses are disconnected. They're available on standard and Enviro-Guard® hoses as well as individual adapters. Related "Robinair" Product Information AC Gauges & Hoses - Index Page Full Product Listing - Index Page
