RectorSeal 87044 Pro-Fit 1/2" Quick Connect Service Valve, Push-to-Connect Refrigerant Fitting
The 87044 handles the suction side. It is the same equipment-mounted Pro-Fit valve architecture as the smaller sizes — brass body, copper stub brazed into the unit's circuit, two-hole mounting flange, capped service port, capped operating stem — scaled to a 1/2" lineset connection. On the suction side the payoff is larger: 1/2" is where hand-flaring gets physically awkward and where a compromised flare vents the most refrigerant. Replacing that connection with a push port at 1-1/4" of insertion removes the step entirely, at 870 psig and 250°F continuous.
Is a 1/2" Service Valve the Right Part for This Job?
The same two qualifiers apply as at the smaller sizes. The equipment end is a copper stub requiring a brazed joint, so this is a part that goes onto a machine rather than into a lineset run, and RectorSeal offers the valves on an OEM basis rather than as part of the general five-fitting line. If you only need to get a 1/2" lineset onto an existing flare port, the 87038 socket does that with no brazing.
The 1/2" body is noticeably larger than the 1/4" and 3/8" valves — RectorSeal ships it in a wider carton, still 5 to a box. Allow for that bulk when planning the mounting location and the clearance around the service port and stem caps. The lineset goes into the push port at 1-1/4" of insertion, with no nut and no torque on that connection; isolate or pump down the system before releasing it later.
Ideal for: OEM equipment specifying push-to-connect suction connections at 1/2", replacing a failed factory suction service valve, and builds where removing the 1/2" field flare — the most awkward one to cut well — is the design intent.
Largest valve in the range? That is the RectorSeal 87045 Pro-Fit 5/8" Quick Connect Service Valve. To splice 1/2" tube to tube in the field, use the 87020 union coupling.
Confirm the valve's connection type, mounting pattern, and application against RectorSeal's documentation and the equipment manufacturer's requirements before specifying. 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 size lineset does the 87044 accept?
1/2" O.D. tubing, into the push-to-connect port. The opposite end is a copper stub brazed into the equipment, not a second tube connection.
Is the 87044 the same body as the smaller valves?
Same architecture, larger body. RectorSeal ships the 1/2" and 5/8" valves in a wider carton than the 1/4" and 3/8" sizes, still five to a box — allow for the extra bulk when planning the mounting location and cap clearance.
Does the 87044 include a valve core and cap?
The valve ships with its service / access port and operating stem both capped. RectorSeal does not publish a written specification for what sits beneath the service port cap — confirm the port's internals and thread with RectorSeal before assuming a particular core or hose connection.
What has to happen before disconnecting the push port on the 87044?
RectorSeal's instructions are explicit: the refrigeration system must be isolated or pumped down before disconnecting. Only then is the disconnect clip used to release the tube.
Is the 87044 rated to the same 870 psi as the fittings?
Yes. ICC-ES PMG-1616 covers the service valves alongside the unions, elbows, reducers and sockets at 870 psig design pressure and 250°F continuous operating temperature across all sizes.
Can the 87044 be retrofitted to an existing condenser?
It can replace a failed service valve where the equipment's circuit and cabinet accommodate the brazed stub and the two-hole flange, which is a fabrication question specific to that unit. Confirm compatibility with the equipment manufacturer before planning a retrofit.
