RectorSeal 87042 Pro-Fit 1/4" Quick Connect Service Valve, Push-to-Connect Refrigerant Fitting
The RectorSeal 87042 is the equipment-mounted member of the Pro-Fit family. Where the unions splice tube to tube and the sockets adapt to a flare port, this is the valve that mounts to the machine itself: a brass body with a copper stub on the equipment side, a two-hole mounting flange, a capped service port, a capped operating stem, and — in place of the flare connection an installer would normally have to cut — a 1/4" Pro-Fit push-to-connect port for the lineset. It carries the same 870 psig design pressure and 250°F continuous rating as the rest of the line.
Is a 1/4" Service Valve the Right Part for This Job?
This is not an inline fitting. The equipment side terminates in a plain copper stub that has to be brazed into the unit's circuit, and the flange bolts to the cabinet sheet metal — so the valve goes on a machine, not into the middle of a lineset run. RectorSeal offers the service valves on an OEM basis, which is the clearest signal of intent: they are specified into equipment or fitted when an existing valve is replaced, rather than carried as a general-purpose repair part.
What it changes for the installer is the connection at the unit. The lineset goes into the 1/4" push-to-connect port at 1" of insertion — cut square, deburr, mark, push until the grip ring clamps, tug-test — with no flare to cut and nothing on that port to torque. The service port and the stem stay capped until the system is being charged or serviced.
Ideal for: OEM equipment builds specifying push-to-connect lineset connections, replacing a damaged or leaking factory service valve on a 1/4" liquid connection, and installations where eliminating field flares at the unit is the goal from the design stage rather than a field workaround.
Not mounting to equipment? To adapt a lineset to an existing flare port, use the 87036 1/4" socket. To splice tube to tube, use the 87018 1/4" 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.

One complete valve per unit with the push-end seal stack factory-assembled and both port caps fitted. RectorSeal cases the service valves 5 per box rather than the 10 used for unions and elbows — the valve body is roughly twice the bulk, and the case carton is the same size as the matching union's. The 87048 Pro-Fit Support Kit provides the depth gauge and disconnect clips for the push port.

Frequently Asked Questions
What are the connections on the 87042?
A 1/4" Pro-Fit push-to-connect port for the lineset on one side, and a copper tube stub on the equipment side that brazes into the unit's circuit. It also carries a capped service port, a capped operating stem, and a two-hole mounting flange.
Is the 87042 a shutoff valve or just an access port?
The body carries both a capped service/access port and a separate capped operating stem, which is the architecture of a stop valve rather than a plain access tee. RectorSeal does not publish a written description of the stem's operation — confirm the valve's function with RectorSeal for your specific application before specifying it.
How does the 87042 mount?
Through a flat brass flange cast into the body with two mounting holes, intended to bolt to equipment cabinet sheet metal. The flange is stamped with the refrigerant designation and a lot code.
Is the 87042 an OEM part?
RectorSeal's own product announcement states that the service valves in 1/4", 3/8", 1/2" and 5/8" are available on an OEM basis, and lists the general Pro-Fit line as the union, 90° elbow, reducer, 90° elbow reducer and socket. Treat it as an equipment-level component rather than a general repair fitting.
How deep does the lineset seat in the 87042?
1" into the push-to-connect port, the same as every other 1/4" Pro-Fit fitting. Mark it with the depth gauge, push until the grip ring clamps, and tug-test. There is no torque on that port.
Why are the service valves cased 5 per box?
Carton volume. RectorSeal ships the 1/4" valve in the same carton as the 1/4" union but with half the pieces — the valve body is roughly twice the bulk of a union, so the same box holds five instead of ten.
