1/2 inch x 1/4 inch Brass Compression Reducer Reducing Adapter Lead-Free Male x OD

Contractor-Grade BrassCraft 68-4-8X Compression Adapter – 1/4 inch OD x 1/2 inch MIP

The BrassCraft 68-4-8X compression adapter is a precision-machined brass fitting engineered to transition from a 1/4-inch outside diameter compression line to a 1/2-inch male iron pipe (MIP) thread. This fitting is frequently used in potable water and gas distribution systems where corrosion resistance, secure mechanical grip, and code compliance are critical.

Built for Reliable System Integration

• ✅ Material: Lead-free forged brass for compliance with federal and state potable water requirements (including NSF/ANSI 61 & 372 certifications).
• ✅ Connection Type: 1/4” OD compression x 1/2” MIP thread – precision-machined for tight, leak-resistant joints.
• ✅ Operating Pressure: Rated for up to 200 PSI in water systems and up to 125 PSI for air/gas where permitted by local codes.
• ✅ Temperature Range: -65°F to 250°F operating temperature range for reliable performance under thermal stress.
• ✅ Corrosion Resistance: High brass alloy composition resists dezincification and is suited for indoor and outdoor installations.

Installation Notes

This adapter is installed without solder or heat, relying on a mechanical ferrule and compression nut for sealing. Ensure proper torque specifications are followed to prevent over-compression. Plumber’s tape should be applied only on the MIP threads during installation; avoid applying sealant to compression threads.

Common Applications

Widely used in water heater installations, appliance hookups, and transition points between copper tubing and threaded iron or brass pipe. Especially useful in retrofit environments where minimizing heat exposure is required.

Code Compliance and Safety

Complies with the Safe Drinking Water Act (SDWA) and is certified lead-free per NSF/ANSI 372. It meets UPC and IPC requirements for brass compression fittings used in residential and commercial water distribution systems.

Key Advantages

• ✅ Secure, flame-free joint construction reduces fire risk in occupied structures.
• ✅ Mechanical grip and seal eliminate the need for curing or cooling times.
• ✅ Brass body resists deformation and maintains structural integrity under torque.

For professionals seeking a robust, compliant connection between 1/4 inch OD tubing and 1/2 inch MIP outlets, the BrassCraft 68-4-8X adapter provides a field-proven solution. Designed for ease of installation and long-term reliability, it supports efficient workflows on new construction, remodels, or emergency repairs.
