We supply Reverse Osmosis, RO and HMA plumbing fittings, Aquarium Auto Topup Fittings all for aquarium use. Our plumbing fittings are totally inert to the erosion affect of Reverse Osmosis, RO water and especially in salt water systems. Our Reverse Osmosis, RO plumbing and aquarium auto top systems do not contain copper which is attacked by Reverse Osmosis RO water.
Reverse Osmosis RO fittings simply push together with a little force.
