Nibco NIB-PC7/8-90ST Pressacr 7/8 Inches Od Wrot Copper 90 Degree Long Radius Elbow Fitting Press X Press

Product Description

The NIBCO NIB-PC7/8-90ST is a wrot copper PressACR 90-degree long radius elbow fitting designed for use in air conditioning and refrigeration piping systems. This fitting connects two sections of 7/8-inch OD copper tubing at a 90-degree angle using a flameless press connection method, making it a fast and reliable choice for HVAC technicians and refrigeration contractors. The fitting features an inboard bead and a gray HNBR O-ring that compresses tightly around the tube wall when a standard pressing tool is applied. No flame, solder, or flux is required, which reduces fire risk and eliminates the need for hot work permits on job sites. The long radius design provides a gradual directional change of 90 degrees, which reduces turbulence and pressure drop in refrigerant lines compared to short-radius elbows. One end features a male fitting connection that can be soldered or pressed, while the other end accepts a press connection. This dual-end configuration gives installers added flexibility when transitioning between press and sweat connections in the same system. Wrot copper construction ensures excellent corrosion resistance, thermal conductivity, and durability across a wide range of operating pressures and temperatures found in commercial and residential HVAC-R applications. The press fitting system is compatible with standard ACR copper tube used in refrigerant piping. This fitting is manufactured in the USA and sold individually. It is well suited for new installations, retrofits, and repairs where a long-sweep 90-degree elbow is needed and where speed of installation is a priority.

• Flameless press connection installs in seconds with no solder, flux, or open flame required
• Long radius 90-degree sweep reduces pressure drop and turbulence in refrigerant lines
• Gray HNBR O-ring and inboard bead provide a clean, leak-resistant seal under pressure

Product Highlights

The NIBCO NIB-PC7/8-90ST delivers fast, flameless installation for 7/8-inch OD ACR copper piping systems. Its long radius elbow design and wrot copper construction make it a dependable choice for HVAC-R technicians working on refrigerant piping.
