24 pt bottles of black gold vacuum pump oil. Black Gold Vacuum Pump Oil is the gold standard in vacuum pump care. For use in any vacuum pump, Black Gold is extremely pure and non-detergent. Our Black Gold is hydro processed, meaning it goes through a series of catalytic steps rendering the oil extremely refined, more viscous, and more stable. The result is clear mineral oil which will alert you to contamination sooner as it becomes cloudy or milky. In extreme temperatures, the oil will be more resistant to contaminants. We still recommend, however, that the oil be changed after every evacuation for maximum performance and pump efficiency. The best test to see if your oil is contaminated is through a micron gauge. With a leak-free system, if your DV-22N micron gauge is still not reading a deep vacuum, the oil is too contaminated and should be changed. If the micron gauge pulls down to about 50 micron the oil is good.

JB Industries Kobra CCLV-6 Kevlar High Pressure Charging Hose Set with CLV-6 series hoses feature a ball valve 6" whip end with ball valve that opens to full flow. These can be used as replacements for the CLV Kobra high pressure series or to connect to other hose fittings. Our patent pending design of the fittings features a hood that locks the gasket into the fitting with a straight edge to straight edge force that eliminates the blowout of the gasket. The barbed depressor locks into the gasket, exuding more outward force and pushing the gasket further into place. This depressor is precisely machined for maximum flow and has a dimple that guides the valve core into place. Kobra high pressure hoses are made from Kevlar - the same material that stops bullets in bullet-proof vests. Kevlar makes our hoses strong and flexible, while the nitrile cover extends the life of the hoses better than neoprene. Kobra hoses are made in the USA.,
