Nalgene PVC Hand-Operated Vacuum Pumps with Gauge are ideal for siphoning, filtration, liquid transfer, bleeding fluid lines, and checking for leaks

Lightweight units are sealed and self-lubricating with removable covers on exhaust port and trigger to release vacuum without disconnecting pumps from the line. New handle design is more durable and ergonomic. Vacuum trigger release requires only one hand to operate and releases vacuum with the touch of an index finger.
