Spring Operated Check Valve

Prevents damage to air source from back siphoning in the event of accidental loss of power, power failure, or "brown-out". Will not allow water to reach valuable air pumps or damage caused from water in the airline.

To install, simply cut the airline at a convenient location between the air pump and its first outlet. One valve per package. Fits standard airline tubing only. Each valve measures approximately 1-1/4" inches in length.
