Common Applications

The Bykski CC-DTJ-SR is a stainless steel server-grade P-Lok dual-thread coupler used to join two threaded ports inside a custom water cooling loop while maintaining a high-flow internal path. The 24-degree tapered ferrule creates a metal-on-metal sealing contact at the mating face rather than relying solely on an O-ring, which improves long-term reliability under pressure cycling and vibration. SUS construction with EPDM secondary seals suits continuous-duty server loops where brass or chrome-plated parts would degrade. The CC-DTJ-SR family ships in several thread/barb size combinations (G1/8, G1/4 and G1/2 thread sides paired with 14mm or 22mm barb couplers), so the same series can adapt between common DIY standards and server P-Lok ports.

Frequently Asked Questions

Q: What is the CC-DTJ-SR used for?

A: It is a dual-thread coupler that joins two threaded ports in a custom water cooling loop, using a 24-degree tapered ferrule sealing geometry.

Q: What size variants are available?

A: The CC-DTJ-SR line ships in multiple thread/barb sizes including G1/8 to 14mm, G1/4 to 14mm, and G1/2 to 22mm couplers.

Q: Is the body fully stainless steel?

A: Yes, the body is SUS stainless steel and the sealing rings are EPDM, both selected for continuous coolant exposure.

Q: Can it be used in server racks?

A: Yes. The SS body and metal-on-metal ferrule seal are designed for vibration resistance and long service life in rack-mounted server loops.

Q: Does it loosen under thermal cycling?

A: The 24-degree tapered ferrule provides a metal-to-metal seal that is more resistant to creep and vibration loosening than O-ring-only fittings.
