QD Plug and Socket Bodies
We manufacture precision-machined QD plug and socket bodies for liquid cooling quick disconnect assemblies. These metal components form the main structures of the male and female ends, with precision-machined bores, threads, locking interfaces and seal grooves. Manufactured to customer drawings, our components can be used in dry break quick disconnect and non spill quick disconnect designs when the required product structure and sealing specifications are supported. Available materials include SS304/SS316L stainless steel, brass and aluminum alloy.

Applications
Our QD plug and socket bodies are machined for male and female interfaces in liquid cooling quick disconnect assemblies, including designs requiring controlled sealing and fluid disconnection.
Male End of Quick Disconnect Assembly (Plug)
Plug Body serves as the main body of the male quick disconnect end, carrying valve core installation, locking structure positioning, and external thread interface machining to ensure accurate mating with Socket Body
Female End of Quick Disconnect Assembly (Socket)
Socket Body serves as the main body of the female quick disconnect end, featuring valve core mating chamber, internal thread interface, and seal groove machining for insertion and locking with Plug Body
Internal Bore Mating of Plug and Socket
Coaxiality and bore diameter precision control between plug-end valve core mounting holes and socket-end valve core guide holes, ensuring smooth valve core actuation during mating
Sealing Interfaces for Dry Break Quick Disconnects
Machining of seal groove position, depth, and sealing surface finish on both Plug Body and Socket Body, ensuring uniform seal compression after assembly
Quality Control
Each batch of Plug Body and Socket Body parts undergoes the following quality control procedures:
Incoming Material Inspection
Verification of bar stock material certificates; material grade and sulfur content confirmation; O.D. and straightness sampling inspection

FAQ
Find answers to common questions about our products, services, and support.
What are the key machining differences between Plug Body and Socket Body?
Plug Body typically requires external thread machining, valve core mounting holes, and locking structure locating surfaces. Socket Body requires internal thread machining, valve core guide chambers, and seal grooves. Their bore sizes, thread directions, and sealing structure designs differ, requiring separate machining parameter control per respective drawings.
How does seal groove machining accuracy affect Plug Body/Socket Body performance?
Seal groove depth, width, bottom finish, and edge chamfer directly affect seal positioning and compression. Machining deviations can cause uneven compression or improper installation, affecting mating performance. We strictly control seal groove dimensions within drawing tolerances.
How is the internal bore mating accuracy between Plug Body and Socket Body ensured?
We control bore dimensions and coaxiality through high‑precision CNC positioning and in‑process measurement systems. Critical fit dimensions can achieve tolerances up to ±0.02mm, with SPC monitoring implemented in batch production per customer drawing requirements.
Do external threads on Plug Body and internal threads on Socket Body need to be matched during machining?
Threads are machined independently per respective drawing specifications and accuracy grades. Interchangeability is ensured through thread gauge inspection. We use go/no‑go gauges to inspect threads per batch, ensuring dimensions and accuracy meet drawing requirements.
Do you support prototyping for Plug Body and Socket Body?
Yes, we support prototyping and small‑batch orders to validate plug/socket designs and assembly fit. Lead time and MOQ are determined per drawing and process complexity. Monthly capacity exceeds 100,000 pieces.
