DK-Lok Distributor Australia, Valve and Flow Control Specialists Instrumentation tube fittings, valves accessories and Pipeline ball valves. October 2021.
DK-Lok manufactured in South Korea started from humble beginnings in 1986. They are now technically no 1 nationally in Korea and no 2 globally in this market. Dk-Lok have acquired the certification of ASME N, NPT, NS STAMP. They then further achieved product certification and testing by global certification agencies such as LR, GL, ABS, DNV, RWTUV, NK, and KR. Now they are one of the most certified fittings and valve manufacturers globally . They have achieved this through extensive constant R & D along with ongoing investment in human resources, manufacturing upgrades and resource improvements. DK-Lok is globally recognised by industry to have Instrumentation products technically comparable with Swagelok. We can now say DK-Lok through its commitment to quality, certification and service is second to no other.

Single tube clamps and double tube clamps for Fractional / Imperial tube as well as a small range of metric up to 2 in size.
What materials are DK-Lok Fittings and Valves manufactured from?
The basic materials are Brass, Carbon Steel and 316 Stainless Steel. Exotics are also made like Titanium, Hastelloy, Inconel, Alloy 400, Alloy 600, Alloy 800, Duplex, Super Duplex, Aluminum and PTFE.
Certain Industries also require additional testing and approvals and DK-Lok set the standard for high integrity manufacturing with certifications for the likes of the Semi-Conductor sector (Ultra Clean Fittings and Valves) , Oxygen Service Fittings and Valves, Hydrogen Service Fittings and Valves as well as the CNG / NGV Fittings and Valves.
Refer individual products under Instrumentation – hydrogen – Oxygen and CNG NGV links or industry dropdowns.
DK-Lok compatibility with Swagelok
Twin ferrule tube fittings from both brands have been independently successfully tested to ASTM F1387 (last test revision 2016). This standard encompasses pneumatic and hydrostatic proof testing, Hydrostatic burst testing, tensile pull tests, rotary flex tests, flex fatigue tests and vibration testing. Test results achieved with individual component intermixability between DK-Lok and Swagelok components. To the best our knowledge this is the only successful independant ASTM mix test ever achieved (others if at all only submitted their own brand). Resulting from positive test results DK-Lok issued a global letter of warranty. This covers the full interchangeability and intermixability of correctly assembled fittings from both manufacturers globally. Clients have reinforced these results that have mixed both brand components for over 10 years without a single issue.
