Psyqtsuary Check Valve and T Valve 12 Pack

The Psyqtsuary 12 Pcs set gives you two parts every air system needs: 6 check valves and 6 T shaped air valves. Both fit standard 3/163 aquarium tubing and come in black.

Check valves

A check valve stops water from flowing back down the airline when the power fails or the pump pauses. Without one, a pump sitting below the tank can flood. These are made from sturdy plastic and measure 1.43 x 0.963 x 0.353.

T shaped control valves

A T valve splits air into two directions and has a lever to regulate flow. That lets you fine-tune airflow into a sponge filter and an air stone from the same pump, or trim a strong pump down so it does not churn a small tank.

Building a simple manifold

1. Run tubing from the pump to a check valve.
2. Connect the check valve to a T valve.
3. Run each outlet of the T to a stone, filter or another tank.
4. Adjust each lever until the bubbles look even.

Why black

Black parts blend in against a dark background or stand and pair well with black airline tubing such as the JIH 50 feet black tubing kit.

Tips

Mind the arrow on each check valve; it should point toward the tank. Replace check valves when the airflow weakens, since their seals wear with time. If a T valve leaks at the lever, a drop of aquarium-safe silicone on the outside of the joint is a quick repair, though replacement is easier with spares in the pack.

Who should buy it

This set is useful for a first multi-line setup or for a keeper with two or three tanks on one pump. If you only need check valves, look at the DaToo 12 pack.

Keep the spare parts in a labeled bag near the tank.
