Hailiang 7/845cest 7/8 in Od 45 Deg Copper Elbow Short Radius

Product Description

The HAILIANG 7/845cest is a 45-degree short-radius street elbow machined from copper, sized for 7/8-inch outside-diameter tubing. Street fittings have one male end and one female end, allowing the elbow to connect directly to another fitting without a short coupling in between. That configuration reduces overall assembly length and is a common choice where routing space is tight. Licensed plumbers and HVAC technicians install this type of fitting during refrigerant line, potable water, and hydronic piping work. The short-radius bend produces a tighter turn than a long-radius elbow, which is useful in confined mechanical spaces.

This elbow is suited for residential and light commercial applications involving copper tubing systems. HVAC technicians use short-radius street elbows when routing refrigerant lines around obstructions or when connecting service valves and manifolds. Plumbers reach for them in domestic water piping, drain-waste-vent rough-in, and hydronic heating distribution. The 7/8-inch OD size is a standard dimension in ACR copper tubing, making this a common service and replacement fitting on split-system refrigerant circuits and copper water distribution assemblies.

Key Features

• Short-radius 45-degree bend for tight directional changes in confined spaces
• Street configuration with one male and one female end eliminates an extra coupling
• Sized for 7/8-inch OD copper tubing, a standard ACR and plumbing dimension
• Copper construction is compatible with sweat, braze, and press joining methods
• Sold individually, allowing single-fitting replacement or small-quantity procurement

Compatibility

Designed as an OEM-style replacement short-radius street elbow for copper tubing systems with a 7/8-inch outside diameter, including ACR refrigerant line sets and copper water distribution piping.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber following applicable local mechanical and plumbing codes. Recover and isolate refrigerant or shut off water supply before cutting into an existing line. Clean and deburr all tubing ends, and apply flux evenly before sweating or brazing. When brazing on refrigerant circuits, purge the line with dry nitrogen to prevent internal oxidation scale.
