Brightline MFG 7/8"Coupling With Stop Copper ACR Fitting (2-Pack) – HVAC Refrigeration Elbow, Sweat Solder Connection, 0.75 Inch ID Copper Pipe Connector for AC & Refrigeration Systems R22, R410,R454 — Open-Box, 10% Off

PRECISION Straight Coupling With Stop ACR — Engineered from wrot copper for smooth, uniform sweat solder cups that seat tight every time, minimizing refrigerant flow restriction versus cast fittings in tight AC and refrigeration line sets. BUILT FOR HVAC & REFRIGERATION SYSTEMS — Sized for 7/8" (0.75") ID copper tubing, this ACR-grade elbow is the trusted choice for split systems, condensate lines, mini-splits, and commercial refrigeration installs where directional offsets under 90 degrees are needed. RELIABLE SWEAT CONNECTION, EVERY BRAZE — Wrot copper's thinner, consistent wall structure heats evenly and bonds faster than cast alternatives, giving technicians a cleaner braze joint with less torch time and fewer leak callbacks. UNIVERSAL FIT FOR LINE SET & MINI SPLIT INSTALLATIONS — Sized for 7/8 inch OD copper tubing, this versatile fitting works with ductless mini splits, heat pumps, condensers, and traditional split AC systems alike. Please note: engineered specifically for HVAC refrigeration lines and will not fit standard household plumbing pipe. USA-BASED SUPPORT & LIMITED LIFETIME WARRANTY — Skip the guesswork of imported fittings with inconsistent wall thickness. Every fitting is quality-checked and backed by a USA-based company with a limited lifetime warranty, so you can install with confidence on new jobs or emergency repairs alike. UNIVERSAL HVAC COMPATIBILITY: Specifically rated to handle high-pressure environments up to 700 PSI at standard operational limits. Perfect for residential or commercial R-22,R-410A, R454,R-32 split-systems, ductless mini-splits, and industrial refrigeration equipment.

Brightline MFG 7/8" Straight Coupling With Stop Wrot Copper ACR Fitting (2-Pack)

When your line set needs a precise directional offset without the flow restriction of a coupling, the Brightline MFG 7/8" Straight Coupling With Stop Wrot Copper ACR Fitting delivers the fit, strength, and reliability HVAC professionals demand.

Why Wrot Copper Makes the Difference

Unlike cast copper fittings with inconsistent wall thickness, wrot (wrought) copper is formed from drawn copper tube, giving this elbow a smoother interior surface and uniform sweat solder cups. That means faster, more even heating during brazing, stronger joint bonds, and fewer leak points over the life of the system.

Built for AC & Refrigeration Applications

• Fits standard 7/8" (0.75" ID) copper tubing
• Straight Coupling With Stop for connecting in line sets
• Ideal for split-system AC, mini-splits, heat pumps, and commercial refrigeration
• ACR-grade construction rated for system pressures and long-term durability
• Sweat solder cup connections on both ends for standard brazing installation

What's Included

This listing includes 2 (two) 7/8" Straight Coupling With Stop wrot copper ACR elbow fittings — enough for two connections on the job or a backup fitting to keep in your kit.
