Questions & Answers

This elbow adapter has a 3/8" compression male outlet with an outside diameter of 0.56" (14.22 mm), and a 1/2" BSP (G) female inlet with an inside diameter of 0.73" (18.63 mm).

No. The 3/8" compression male side is designed for fittings that mate with a 0.56" (14.22 mm) OD, not 0.61". If your tube or nut is based on 0.61" OD, this adapter will not be compatible.

The 1/2" female side is BSP (G) thread, also referred to as 1/2 G. It is not a 1/2" NPT thread and will not properly seal with NPT-only male fittings.

No washer is required. The 1/2 G female end does not have a flat sealing surface inside; it is intended to be sealed with PTFE (Teflon) tape on the male threads.

Yes. This adapter is specifically intended to connect a 3/8" compression line to a 1/2" BSP (G) angle stop or valve, providing a 90-degree elbow transition.

The adapter is made of stainless steel, which is commonly used for potable water applications. However, always check your local plumbing codes and system requirements to confirm compatibility.

It is sold as a pack of 2 adapters. Each pack includes two identical 90-degree elbow fittings.

Yes, as long as the hose end is 3/8" compression compatible with a 0.56" OD male and the valve or fitting on the other side is 1/2" BSP (G) male, this adapter will work.

No special tools are required beyond standard plumbing tools. Wrap PTFE (Teflon) tape on the 1/2" BSP male threads you are connecting to, then tighten the adapter with an appropriate wrench, taking care not to overtighten.

Yes. The 90-degree elbow design is suitable for tight spaces such as behind toilets or under sinks, helping to route the 3/8" line neatly from a 1/2" angle stop.
