Threaded connector PARTNER PA-MM06/04 — external thread 3/8" x 1/4"

Threaded connector PARTNER PA-MM06/04 — external thread 3/8" x 1/4" is a compact metal fitting designed to join pipes, hoses or other fittings that use 3/8" and 1/4" external thread standards. The connector provides a mechanical and fluid-tight joining solution for installations and repair work in plumbing, pneumatic or low-pressure hydraulic systems where these thread sizes are required. Its straightforward design focuses on reliable alignment and straightforward assembly when connecting components with matching internal threads.

Advantages

The metal construction ensures durability and resistance to mechanical wear in typical installation conditions. The precision external threads enable consistent mating with compatible internal-threaded components, reducing the risk of leaks when assembled correctly. Its compact dimensions allow use in confined spaces and simplify retrofits or replacements without major layout changes. The neutral finish and standardized thread sizes make it compatible with a wide range of fittings and hoses that follow the same thread conventions.

Suitable for

• Connecting plumbing components such as valves, adapters and flexible hoses
• Pneumatic lines and equipment requiring 3/8" to 1/4" threaded transitions
• Low-pressure hydraulic circuits and small fluid transfer systems
• Maintenance, repair and retrofit tasks in domestic or workshop installations

Key specifications

• Type: threaded connector with external threads
• External thread sizes: 3/8" and 1/4"
• Material: metal construction suitable for mechanical joining (corrosion resistance depends on alloy and finish)
• Form factor: compact inline fitting for connecting two threaded components
• Application pressure: suitable for plumbing, pneumatic and low-pressure hydraulic uses (verify system pressure compatibility before use)

How to use

Select components with matching internal thread sizes (3/8" and 1/4") and ensure threads are clean and undamaged. Apply an appropriate thread sealant or tape if the application requires a fluid-tight seal, following the sealant manufacturer's instructions. Hand-start the connector onto the mating threads to avoid cross-threading, then tighten with suitable tools until a secure fit is achieved without over-tightening. After assembly, inspect the joint for alignment and test under working conditions to confirm there are no leaks.

Usage recommendations

Use thread sealant or PTFE tape for fluid-carrying applications where a leak-free connection is required, and confirm material compatibility with the media being transferred. For pressurized systems, verify the connector and mating parts meet the system's maximum working pressure. When installing in confined spaces, avoid excessive torque and consider using a backup wrench to prevent twisting the connected components.
