Aquarium Pressure Gauge 220 PSI Reverse Osmosis MALIDA

OPEN BOX

Stainless Pressure Gauge 220 PSI with fitting for use with reverse osmosis systems, aquariu, marine systems and all water filter systems

Designed to use an O-ring to create a water tight seal, simply drop a small O-ring ( I believe size #011) into fitting

You will find this creates an instant seal even when it’s only hand tight
