This pair of nipple cylinders have quick connect safety valves which can be attached easily to most standard pump hoses and disconnected with the push of a button. When released, they maintain the vacuum, so you can pump each side individually without the need for a T-hose connector.Pump required, sold separately.

PLEASE NOTE: This item includes two cylinders only. For this to function, you must have a compatible pump, such as the Heavy Duty Dry Brass Hand Pump with ANSI Gauge sold at FullKit.com.
