Description
Product Overview
Gadoutcover brass reducing nipples are precision-engineered pipe fittings designed to connect female pipe fittings with different diameters. These solid brass connectors feature NPT taper threads that ensure tight seals and prevent leakage in various industrial and plumbing applications. Available in multiple size combinations including 3/4 NPT to 1/4 NPT, 1/2 NPT to 1/4 NPT, and other configurations, each package contains 2 pieces of these durable brass reducers. The fittings operate effectively within a temperature range of -65°F to +250°F (-53°C to +121°C) and can handle pressures up to 1200 psi. With dimensions of 3 x 2 x 1 inches and deep, accurate threading, these brass nipples provide reliable performance in compressed air, hydraulic, refrigeration, and gas systems.

Usage
These brass reducing fittings are ideal for industrial, commercial, and residential plumbing systems where connecting pipes of different diameters is necessary. They serve perfectly in compressed air lines, hydraulic systems, refrigeration units, and gas piping applications. Professional plumbers, HVAC technicians, and industrial maintenance crews will find these fittings essential for extending pipe lengths or adapting between different pipe sizes. The fittings work effectively in water supply systems, pneumatic tools connections, and instrumentation setups where reliable, leak-proof connections are critical. Homeowners undertaking DIY plumbing projects can also benefit from these easy-to-install brass reducers for various repair and installation tasks.

FAQ
What does NPT thread mean?
NPT stands for National Pipe Taper, which is the U.S. standard for tapered threads used in pipe fittings. The taper allows the threads to create a tighter seal as they’re screwed together, making these fittings ideal for preventing leaks in pressurized systems.
Are these fittings suitable for gas line applications?
Yes, these brass reducers are appropriate for gas line connections when used within their specified pressure and temperature ratings. The solid brass construction and precise NPT threads provide reliable, leak-resistant seals suitable for gas, compressed air, and other media.
Do I need thread sealant with these fittings?
While the NPT taper threads are designed to create seals without additional materials, using thread seal tape or compound is recommended for critical applications to ensure complete leak prevention, especially in high-pressure systems.
What sizes are available in this product line?
The Gadoutcover brass reducers come in multiple size combinations including 1/2 NPT x 1/4 NPT, 3/4 NPT x 1/2 NPT, 1/2 NPT x 3/8 NPT, 3/4 NPT x 1/4 NPT, and 1/4 NPT x 1/8 NPT. Each option includes 2 pieces of the specified size combination.
Can these be used with stainless steel pipes?
Yes, these brass reducers work well with stainless steel, copper, and other common pipe materials. The brass material is compatible with most industrial piping systems and provides excellent corrosion resistance in mixed-material applications.
