Nibco NIB-PC3/4-90ST Pressacr 90 Degree Long Radius Elbow Fitting 3/4 Inches Od Press X Press Wrot Copper

Product Description

The NIBCO NIB-PC3/4-90ST is a wrot copper PressACR 90-degree long radius elbow fitting designed for use in refrigerant and HVAC piping systems. It features a 3/4 inch OD press connection on one end and a male fitting end on the other, allowing the pipeline direction to change by 90 degrees between a press connection and a fitting connection. The fitting connection end can be either soldered or pressed, giving technicians flexibility on the job. This elbow is built with an inboard bead and a gray HNBR O-ring. When a pressing tool applies force to the fitting, the O-ring is compressed tightly onto the tube, creating a clean, leak-resistant mechanical seal in seconds. No open flame, solder, or flux is required. This makes the NIB-PC3/4-90ST a fast and reliable choice in tight spaces, occupied buildings, or anywhere open flame is a concern. The long radius design provides a gradual directional sweep, which reduces pressure drop and flow restriction compared to a standard short radius elbow. HVAC technicians and refrigeration contractors use long radius elbows when system efficiency and smooth refrigerant flow matter. The wrot copper construction delivers excellent corrosion resistance, pressure handling, and durability across a wide temperature range. Copper fittings have long been the industry standard in refrigerant and plumbing piping, and the PressACR system builds on that legacy with a press-fit installation method that speeds up rough-in work and reduces callback risk. The fitting measures approximately 1.12 inches in height, 2.57 inches in length, and 2.27 inches in width, and weighs 0.166 pounds. It ships individually and is manufactured in the USA. Ideal for ACR copper tubing applications in split systems, chillers, heat pumps, and commercial refrigeration.

• Press-fit installation requires no flame, solder, or flux — creates a secure seal in seconds using a standard pressing tool
• Gray HNBR O-ring and inboard bead design ensures consistent, leak-tight compression onto the copper tube
• Long radius 90-degree elbow reduces pressure drop and supports smooth refrigerant flow in ACR piping systems

Product Highlights

The NIBCO NIB-PC3/4-90ST delivers fast, flame-free installation in a wrot copper long radius elbow built for ACR and HVAC refrigerant piping. The PressACR press-fit design saves labor time while meeting the demands of professional refrigeration and air conditioning work.
