Fittings - Compression
Drip Irrigation Compression Fittings: Drip Irrigation Compression fittings are among the most common connection style fittings used in Drip Irrigation systems to connect sections of either 1/2" or 3/4" solid drip irrigation tubing or soaker hose dripline. Drip Irrigation Compressing fittings work by way of an internal compression ring that squeezes the outside diameter of the drip tubing as it is inserted into the drip irrigation fitting. The angle of the compression fitting ring bites into the soft tubing to prevent it from slipping off and also creates a water tight seal. Drip Irrigation Compression fittings are more of a permanent connection and are not recommended for reuse. For .700 and .710 series reusable/removable drip irrigation fittings, please see our Direct-Loc fittings section.
