RectorSeal 87048 Pro-Fit 1/4" to 5/8" Quick Connect Support Kit, Push-to-Connect Refrigerant Fitting Tools
Every Pro-Fit connection depends on one number: how far the tube goes into the fitting. The 87048 is the kit that makes that number repeatable and makes a joint reversible. It holds a four-step line-marking tool covering 1/4" through 5/8" and four disconnect clips, one for each of those sizes — five pieces that turn "push it in until it feels right" into a marked line and a verified seat, and that let you release a fitting later without cutting the lineset. If you stock Pro-Fit fittings at all, this is the kit that belongs on the van.
What the Support Kit Actually Solves
Insertion depth is the single most common failure point on a push-to-connect refrigerant joint. The seat varies by size — 1" at 1/4", 1-1/4" at 3/8" and 1/2", 1-5/16" at 5/8" — and a tube that stops short leaves the grip ring and O-rings off their sealing surfaces. A tape measure and a marker will do it, but not quickly and not consistently across a dozen connections. The line-marking tool slips over the prepared tube end and puts the mark in the right place every time.
The disconnect clips solve the other half. A Pro-Fit fitting is designed to release, but only with the correct clip pressing the collar — which is what makes it possible to rework a joint, swap a component, or correct a routing mistake instead of cutting the fitting out. RectorSeal's instructions are firm on the sequence: the system must be isolated or pumped down before any fitting is disconnected.
Ideal for: Any contractor stocking Pro-Fit unions, elbows, reducers, sockets or service valves in 1/4" through 5/8"; first-time Pro-Fit users who need the depth marks to be right; and service techs who need the ability to release a joint in the field without destroying the fitting.
Working larger lines? This kit stops at 5/8". For 3/4" and 7/8" fittings you need the RectorSeal 87049 Pro-Fit Support Kit for 3/4" to 7/8", whose tools are sized differently and are not interchangeable with these.
These are installation tools, not pressure-containing components. Use them in accordance with RectorSeal's published instructions. Any refrigerant work must be performed by an EPA 608-certified technician, and the system must be isolated or pumped down before disconnecting a fitting.

What's Included
| Kit | 87048 — Pro-Fit Quick Connect Support Kit, 1/4" to 5/8" (one kit, five pieces) |
|---|---|
| Disconnect Clips | Four clips — one each for 1/4", 3/8", 1/2" and 5/8" |
| Line Marking Tool | One four-step plastic depth gauge covering all four sizes |
| Size Range | 1/4", 3/8", 1/2", 5/8" |
| Insertion Depths Marked | 1" (1/4"), 1-1/4" (3/8" and 1/2"), 1-5/16" (5/8") |
| Material | Molded Plastic |
| Compatible Fittings | Pro-Fit Unions, Elbows, Reducers, Elbow Reducers, Sockets, Service Valves |
| Certification | Not UL listed — UL certifications apply to the brass fittings |
| Case Quantity | 10 kits per manufacturer case |
| Sold As | One complete kit |
Sold as a single kit containing all five pieces — not as an individual clip. One 87048 covers the entire small-to-mid Pro-Fit range, so a van carrying 3/8" unions, 1/2" elbows and 3/8" sockets needs one kit, not three. See the full range on the RectorSeal brand page.

Specifications & Manuals
Product documentation includes the full Pro-Fit part number table, the insertion depth chart this kit's marking tool is built around, and the ICC-ES PMG product rating certificate covering the brass fittings. Note that RectorSeal has introduced a second-generation support kit under separate part numbers; this listing is for part 87048.
Frequently Asked Questions
Exactly how many pieces are in the 87048 kit?
Five. Four disconnect clips — one each for 1/4", 3/8", 1/2" and 5/8" — plus one four-step line-marking tool that covers all four sizes in a single molded piece.
Do I need this kit to install Pro-Fit fittings?
The marking tool is how RectorSeal's own procedure sets the insertion depth, and the clips are the only way to release a fitting without destroying it. You can mark a tube with a tape and a marker, but nothing else will disconnect a Pro-Fit joint.
Will the 87048 clips work on 3/4" or 7/8" fittings?
No. This kit tops out at 5/8". Large-diameter fittings need the 87049 kit, whose tools are sized for 3/4" and 7/8" and are not interchangeable with these.
Is the 87048 sold as a kit or as a single clip?
As a complete kit — all five pieces in one package, sold individually. RectorSeal cases them 10 kits per box for distribution.
Can I disconnect a fitting while the system still holds refrigerant?
No. RectorSeal's instruction is explicit: "The refrigeration system must be isolated, or pumped down before disconnecting." Recover or isolate first, then use the clip.
Is the support kit UL listed like the fittings?
No. RectorSeal's literature marks the support kits "Not UL listed." The UL 207 and UL 1963 certifications under ICC-ES PMG-1616 apply to the brass pressure-containing fittings, not to these plastic installation tools.
