8mm hose barb x 8mm hose barb ball valve (0.31"). Recommended for pipe with 5/16" I.D. (8mm or a little bit smaller) (The mark "1/4" on valves body is the inner size of the valves, not the barb size)
The ball valves are mainly used for on-off controlling or flow adjustment of water, oil, and gas. Typical usage includes garden irrigation system, piping system, water pump, compressor, oil and gas supplying system, hot and cold water systems
for all types of tubing. Insert the barb into the tubing, and fix it with a pipe clamp for a tight seal(Clamps are NOT included here).
If the barb is too large for the tubing, you can dip the tubing into boiling water or use a hot air gun. A little bit heat would help to expend the tubing to fit perfectly
Constructed of durable and corrosion-resistant brass. Rubber-covered operation handle for non-slip control. (Total Length: 47mm, Handle Length: 49mm)
