1/4-in. drip blank distribution tubing or “spaghetti” tubing has a nominal outside diameter of 0.25 in. and internal diameter of 0.17 in. It is made of durable, flexible low-density polyethylene (LDPE) which makes it suitable for a variety of landscape designs. 1/4-in. drip blank distribution tubing can either come directly off the hose faucet via a 3/4-in. female hose thread (FHT) x 1/4-in. Drip-Lock adapter, off a 1/2-in. drip distribution line via a Drip-Lock manifold, or via a 1/2-in. single- or multi-port drip manifold on a 1/2-in. PVC riser. Choose from a variety of 1/4-in. fittings, emitters, and micro-sprinklers to connect tubing and provide water to each plant location. For outdoor irrigation use with cold water only.
