## Summary description

GEKO reduction adapter 3/8" to 1/2" (10/100) is a mechanical fitting that allows connection between 3/8-inch and 1/2-inch threaded components. Supplied in packaging quantity 10/100, it is intended for use in plumbing, hydraulic and pneumatic systems where thread size conversion is needed for hoses, valves or fittings.

## Long description

GEKO reduction adapter 3/8" to 1/2" (10/100) is a mechanical fitting designed to connect components with 3/8-inch and 1/2-inch threaded interfaces. Supplied in packaging quantities of 10 or 100 pieces, the adapter enables thread size conversion without altering system layout. It is intended for use in plumbing, hydraulic and pneumatic systems where compatibility between different threaded parts is required.
Advantages
The adapter provides a secure threaded connection that preserves flow path and pressure conditions typical for the original piping. Manufactured to standard thread dimensions, it allows quick installation and removal with common hand tools. Packaging in multiples of 10 or 100 supports project-scale purchases and reduces the need for frequent reordering.
Suitable for
Converting 3/8" threaded hoses or fittings to 1/2" threaded components
Repairing or modifying household plumbing systems
Adapting valves, couplings and connectors in hydraulic equipment
Connecting pneumatic lines where thread size mismatch occurs
Key specifications
Thread connection: female and/or male 3/8" to 1/2" conversion (standard inch threads)
Material: metal suitable for plumbing and hydraulic use (corrosion-resistant finish where applicable)
Packaging quantity: available in packs of 10 or 100 pieces
Application pressure: suitable for typical domestic plumbing, hydraulic and low-to-medium pressure pneumatic systems (follow system specifications)
Installation: compatible with standard wrenches and hand tools
How to use
Select the correct adapter orientation so that the 3/8" end matches the smaller threaded component and the 1/2" end matches the larger threaded component. Clean threads of both mating parts to remove debris or sealing residues. Apply appropriate thread sealant or tape if required by the system to ensure leak-free joints. Hand-start the threads to avoid cross-threading, then tighten with a wrench to the torque appropriate for the material and application, avoiding over-tightening that can damage threads or fittings.
Usage recommendations
Verify thread types and pressure ratings before installation; use thread sealant compatible with the conveyed medium. For high-pressure hydraulic systems or critical applications, consult system documentation or a qualified technician to confirm suitability.
