Lock Sleeve Fittings
Lock Sleeve Drip Tape CouplingThe lock sleeve drip tape coupling joins standard 5/8 inch tapes drip tight by inserting the tape into each end and turning the locking sleeves. This fitting is also available for 7/8 inch drip tapes. The original lock sleeve concept was developed and engineered by ITC personnel in Hawaii and was the first drip tape fitting of its kind in the world. Available in stock in Hawaii. | ![]() |
Lock Sleeve x1/4 inch Barbed AdapterITC offers the lock sleeve by 1/4 inch barbed adapter to transfer water from lay flat hoses to standard drip tapes (5/8 in or 7/8 in tapes). Note: Other configurations of the locking sleeve fittings are available (tees, elbows, male adapters, barbed shut off valve by lock sleeve, etc.) | ![]() |
The ITC Vacuum Breaker Valve (VBK)The ITC 1 inch vacuum breaker valve (VBK) assembled in Hawaii is available with or without a pressure read option. The picture shown at right includes the optional pressure read. This valve is primarily used for vacuum relief in drip irrigation systems downstream from the block shutoff valves. This relieves a potential vacuum in the drip tape which can cause external drip tape plugging. | ![]() |
