## Long description

The Honiton H-340 reducer adapter converts a 3/8" (female) connection to a 1/2" (male) connection for plumbing installations. Designed as a compact pipe and fitting adapter, it enables connection between fixtures, hoses or valves with different thread sizes. The adapter is suitable for domestic and commercial water supply systems, for tap and valve connections and for repair or replacement tasks where a change of thread size is required.
Advantages
The adapter provides a simple, space-saving solution for adapting a 3/8" female thread to a 1/2" male thread without modifying existing plumbing. Its compact design allows installation in tight spaces and makes it easy to handle during maintenance. The part is intended for direct mechanical connection, reducing installation time and the need for additional fittings.
Suitable for
Connecting faucets, hoses or valves with 3/8" female threads to 1/2" male threaded pipes or fittings
Domestic water supply repairs and replacements
Commercial plumbing installations where thread size conversion is required
Temporary or permanent installations in bathrooms, kitchens and utility rooms
When it may not be suitable
The reducer adapter is intended for standard threaded water connections; it may not be suitable for non-threaded, push-fit or solvent-weld systems. It is not a pressure control device and should not be used where pressure regulation, filtration or backflow prevention is required. Compatibility with non-standard or proprietary thread forms should be verified before installation.
Key specifications
Input thread: 3/8" female
Output thread: 1/2" male
Function: Thread size conversion for plumbing connections
Typical applications: tap connections, hose to pipe adaptation, repair fittings
How to use
Ensure both connection surfaces are clean and free of debris. Screw the adapter into the 1/2" male or female counterpart as required and thread the mating 3/8" fitting onto the adapter until hand-tight. Use appropriate tools to make a final secure connection, taking care not to over-tighten and damage threads or sealing elements. Apply thread sealant or tape if the installation requires a watertight joint according to local plumbing practice. After installation, check for leaks under normal system pressure and re-tighten if necessary.
What to consider before purchase
Confirm that your existing fittings use standard 3/8" female and 1/2" male thread profiles
Verify material compatibility with your plumbing system and the fluids being transported
Check whether additional sealing tape or sealant is needed for a watertight connection
Ensure available space allows access for installation and tightening
Usage recommendations
For reliable results, install the Honiton H-340 reducer adapter with compatible thread sealant and test the connection at normal operating pressure. Do not use the adapter as a substitute for fittings that provide pressure regulation, filtration or backflow protection. If uncertain about thread type or installation, consult a qualified plumber.
