DK-LOK

indSpare is a stockist for DK-LOK, supplying the oil and gas market in the USA and worldwide through the indSpare e-commerce platform. Refineries, petrochemical plants, and EPC contractors source DK-LOK tube fittings, ball valves, needle valves, check valves, and relief valves from our stock.

We carry the full DK-LOK industrial range — instrumentation fittings (1/16" to 1") in 316 SS, brass, and Monel; integral-bonnet needle valves rated to 6,000 psi; ball valves with PEEK and PTFE seats; pressure-relief valves with set pressures from 50 to 6,000 psi. Every fitting we sell is genuine DK-LOK with traceability paperwork on request.

What you get from us versus an overseas drop-ship: same-day dispatch from stock, real lead times on the few items we don't keep on the shelf (typically 3 months), and technical support to cross-reference DK-LOK against existing Swagelok or Parker specs.

Browse the catalogue below or send us your part list. We'll quote within one business day, ship under DAP terms across the USA and worldwide (DDP available on request), and handle customs end-to-end.
