The 1/4" flow DTLD Series dual flow couplings provide a unique thumb latch with independent or simultaneous connections of loose tube sets. Made from ABS thermoplastic, the DTLD Series valved couplings ensures when connecting one insert, the second insert is prevented from disconnecting. One-hand operation makes the DTLD Series the choice for simple, independent connections of dual port connections. The DTLD Series is compatible with all PLC, PLC12 and LC Series Inserts.
