What This Clamp Actually Does
This is a hose separator, not a fitting or a valve — it's a bracket that holds your service and emergency air lines apart from the 7-way electrical cord so they don't chafe or tangle when the tractor swings on a turn. Cheap thing, but if it cracks or the tabs snap off, you get lines rubbing together and wearing through, and that's a roadside call waiting to happen.
It mounts behind the cab on the air/electrical line bundle, universal fit across most Class 7-8 tractors running standard gladhand and 7-way setups. Doesn't matter much if you're running a Freightliner, Kenworth, Pete, or International — the line spacing is pretty standardized industry-wide.
Comes in as a single unit here (TR0292S11), but Tectran sells the same clamp in bulk packs under 34021BULK if you're stocking up for the shop.
Why These Numbers Cross
34022 is the Tectran part number and it's what most fleets reference. Phillips Industries makes the same style clamp and sells it as 17-155 — same design, same purpose, and it interchanges with the Tectran number because both companies build to the same industry-standard spacing for gladhand and 7-way cord separation.
There's no spline count or drum size to worry about here like you'd see on a slack adjuster — this is a simple mechanical clamp. The only thing that matters is the gap width between the tabs and whether it clamps around your specific line diameters. Most heavy-duty air line and cord combos are standard sizing, but if your old clamp looks oversized or has extra mounting holes, snap a photo and compare before you order.
Bottom line: pull the old clamp, check for a stamped number, and match it against what's listed here. If it's worn smooth, measure the tab spacing and line diameter — that'll tell you more than guessing off the truck's badge.
Ordering From PartStop
We're in Tacoma and keep this one on the shelf — if you're local, call ahead and we'll have it up front for pickup same day. Otherwise it ships out same or next business day anywhere in the country.
This is aftermarket, not Tectran-branded stock straight from the manufacturer's warehouse, but it's built to the same interchange spec and backed by our 6-month warranty. For $21.99 there's not much reason to gamble on a cracked bracket holding your lines apart at 65 mph.
If you're not sure this is the right clamp for your rig, give us the number off the old part or your VIN and we'll confirm before you check out. Cheaper to ask than to send it back.
34022 Cross-Reference & Interchange Numbers
These manufacturer and aftermarket numbers commonly cross-reference to 34022. Use them to identify the part — then confirm the exact fit by VIN or the number stamped on your old unit before you order. An interchange is a starting point, not a fitment guarantee.

Frequently asked questions
Does 34022 fit my Kenworth T680?
Most likely, since the T680 runs standard gladhand and 7-way spacing, but pull your old clamp and check the number stamped on it or measure the tab width before ordering. We can also confirm against your VIN if you're not sure.
Is this the same as the Phillips Industries 17-155?
Same style and function, yes — it's a documented cross-reference. Both are separator clamps built to the same industry spacing standard. It's not a Phillips-branded part, but it does the same job and mounts the same way.
Can I buy just one clamp or do I have to get the bulk pack?
This listing (TR0292S11) is the single-unit version. If you need a bunch for shop stock, Tectran's 34021BULK is the case-pack option — ask us and we'll point you to it.
