EasyPro air diffuser manifolds allow you to hook up several air diffusers to a single air line. Manifolds include a check valve to prevent water from filling your air line when not in use. A polyethylene underlay keeps diffusers from settling into the mud or sludge and prevents sediment erosion during operation.

Standard air diffusers are 6" long.

Standard airline connection is ½" poly tubing.

Includes 6 Air diffusers
