It is designed for use in refrigerant and HVAC piping systems where a direction change of 90 degrees is needed. The fitting features one press connection end and one male fitting end, giving installers the flexibility to press or solder the fitting connection side depending on job requirements. HVAC technicians and refrigeration contractors rely on press-fit copper fittings like this one to speed up installation and eliminate open flame work in sensitive environments. The NIB-PC3\/8-90ST includes an inboard bead and a gray HNBR O-ring. When a pressing tool is applied, it compresses the O-ring tightly against the copper tube, creating a leak-free mechanical seal in seconds. No torch, no solder, and no flux are needed on the press side. This makes the fitting ideal for tight spaces, occupied buildings, or any job site where flame work is restricted or impractical. The long radius elbow design allows for a smoother, wider sweep compared to a standard 90-degree elbow. This reduces turbulence and pressure drop in the refrigerant line, which supports system efficiency. The fitting is manufactured from wrot copper, a wrought copper alloy known for its consistent grain structure, strength, and excellent corrosion resistance. It is UL Recognized and NSF Certified, confirming it meets the safety and performance standards required for professional plumbing and refrigeration applications. Country of origin is the USA. Each fitting is sold individually and measures approximately 1.82 inches in length, 1.55 inches in width, and 0.54 inches in height, with a weight of 0.035 pounds. It is a dependable component for copper press ACR piping assemblies in commercial and residential HVAC-R work.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003ePress-fit connection with inboard bead and gray HNBR O-ring for a fast, flame-free, leak-tight seal\u003c\/li\u003e\n\u003cli\u003eLong radius 90-degree sweep reduces pressure drop and turbulence in refrigerant lines\u003c\/li\u003e\n\u003cli\u003eWrot copper construction with UL Recognition and NSF Certification for professional-grade reliability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe NIBCO NIB-PC3\/8-90ST PressACR long radius elbow delivers a code-compliant, flame-free press connection for 5\/16 inches OD copper refrigerant tubing.
