RectorSeal 87027 Pro-Fit 5/8" Quick Connect 90° Elbow, Push-to-Connect Refrigerant Fitting
At 5/8" the suction line stops cooperating with a bender. The tubing is heavy, the minimum radius is wide, and the places these lines have to turn — around a foundation corner, into a lineset cover, up a mechanical room wall — rarely give you that much room. The RectorSeal 87027 makes the turn as a fitting instead: a fixed 90° brass body with a push-to-connect port on each leg, seating 1-5/16" of tube per side with nothing to tighten, holding at 870 psig and 250°F continuous.
Is a 5/8" 90° Elbow the Right Fitting for This Turn?
Five-eighths is the largest diameter still inside the small support kit's range, which makes the 87027 a practical stocking item for crews that service both residential multi-zone and light commercial equipment. It is also the size where the argument for a fitting over a bend becomes the strongest it gets before you reach 3/4" territory: forcing 5/8" copper past its radius collapses the tube and restricts the line, and unlike a liquid line, a restricted suction line shows up in performance immediately.
Both legs seat 1-5/16" — an odd figure that deserves the depth gauge rather than a tape — and neither is tightened, because the fitting has no nuts. What the corner does need is enough clearance to present each tube straight into its port and to see both sight windows. Support the run on both approaches; a 5/8" line carries enough weight that leaving it unsecured puts a constant load on the joint.
Ideal for: Suction line turns at foundation corners and rim joists on 2- and 3-ton systems, routing into and out of lineset covers, vertical rises in mechanical rooms, and replacing a 5/8" corner that was flattened during the original install.
Larger line? Step up to the RectorSeal 87028 Pro-Fit 3/4" Quick Connect 90° Elbow, which also crosses into the larger support kit. For a straight splice at this diameter, use the 87021 5/8" union coupling.
Fitting selection is based on measured tube outside diameter and system operating conditions. Installation must be performed by an EPA 608-certified technician in accordance with RectorSeal's published instructions and applicable mechanical codes.

Frequently Asked Questions
What line size does the 87027 elbow take?
5/8" O.D. tubing on both legs, with no size change through the turn. On most systems where it appears this is the suction line.
How much tube does each leg of the 87027 need?
1-5/16" of insertion per leg. That figure is worth marking with the Pro-Fit line-marking tool rather than a tape measure, since 1-5/16" is easy to round off by eye.
Which support kit covers the 87027?
The 87048 kit (1/4"–5/8"). This is the largest elbow that kit serves — the 3/4" and 7/8" elbows require the 87049 kit instead.
Will forcing a bend instead of using the elbow hurt performance?
Bending 5/8" tubing past its minimum radius flattens the tube, and a restricted suction line affects system performance more directly than a restricted liquid line would. Where the radius will not fit, a full-bore elbow is the better outcome.
Can the 87027 be installed outdoors on an exposed lineset?
Yes. The brass body is UV and corrosion resistant and is built to tolerate vibration and pressure pulsation. Re-insulate over the finished turn to control condensation on a cold suction line.
What holds the tube in the 87027 if nothing is tightened?
A stainless grip ring that clamps onto the tube as it is pushed past full depth, backed by the patented double O-ring stack that does the sealing. RectorSeal's procedure ends with a firm pull on the tube to confirm the grip ring has set.
