Questions & Answers

This adapter has a 3/8" male end with an outside diameter (OD) of 0.52" (13.2 mm) and a 1/2" male end with an OD of 0.75" (19.1 mm). It is designed for systems that use a 3/8" to 1/2" conversion, such as connecting a 3/8" supply line to a 1/2" angle stop. It will not fit 3/8" lines with a 0.61" OD.

It is compatible with standard 3/8" (0.52" OD) and 1/2" (0.75" OD) connections commonly found in RV and residential plumbing. Please measure your existing fittings to confirm the OD matches these dimensions, as it will not work with oversized or non-standard 3/8" fittings (0.61" OD).

It is mainly used to connect a 3/8" water supply line to a 1/2" angle stop, valve, or pipe in RV plumbing systems. This makes it ideal when upgrading fixtures, replacing hoses, or adapting between different line sizes.

The adapter is made from high-quality brass with a premium nickel coating. Brass is commonly used in potable water systems, and the nickel plating adds extra corrosion and rust resistance, making it suitable for RV fresh-water plumbing when installed in accordance with local codes.

Yes. The nickel coating provides an additional protective layer over the brass, improving resistance to corrosion, rust, and wear, which is especially beneficial in the humid and variable conditions common in RV use.

No special tools are required. In most cases, you can install it with standard plumbing tools such as an adjustable wrench. Always avoid over-tightening to protect threads and use appropriate thread sealant or tape if required by your plumbing setup.

Yes. Brass fittings are generally suitable for both hot and cold water applications within typical RV plumbing temperature and pressure ranges. Always ensure your system’s operating conditions fall within standard plumbing specifications.

Each pack includes 5 adapters, allowing you to outfit multiple lines or keep spares on hand for future RV plumbing repairs or upgrades.

While it is marketed for RV use, it can also be used in compatible residential plumbing applications that require a 3/8" male (0.52" OD) to 1/2" male (0.75" OD) adapter, as long as the dimensions and thread types match your existing fittings.

Use a caliper or a ruler to measure the outside diameter of your 3/8" line. If it measures approximately 0.52" (13.2 mm), it is compatible. If it is closer to 0.61", this adapter will not fit and you should select a fitting designed for that larger OD.
