JB's 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 pushing the gasket further into place. The depressor is precisely machined and has a dimple that guides the valve core into place. The depressor is designed to provide maximum flow. Maximum flow, no blowouts, the JB difference.
