Irwin 1794153 250 Series Magnetic Torpedo Level, Die-Cast Aluminum

The Irwin 1794153 250 Series Magnetic Torpedo Level is a compact 9" die-cast aluminum level built for plumbers, HVAC techs, and tradespeople who need fast, accurate readings in tight spaces. Its dual-sided Plumb Site vial design delivers easier, more accurate plumb readings from either side of the tool, while rare earth magnets rated 5x stronger than standard strip magnets allow hands-free, secure attachment to steel and other magnetic surfaces. An integrated 1.5° slope button with a slight radius seats securely on pipe for quick 1/4" per foot drainage checks, and 22.5° and 45° vials help you find common angles fast on the job.

Key Features

  • Durable Die-Cast Aluminum Body: Heavy-duty die-cast aluminum construction stands up to daily jobsite abuse while keeping the compact 9" torpedo level lightweight and easy to carry.
  • Dual-Sided Plumb Site Vial: View the plumb vial from either side of the level for easier, more accurate plumb readings in any working position.
  • Rare Earth Magnets: Built-in rare earth magnets are 5x stronger than standard strip magnets, holding the level securely to steel for true hands-free work.
  • Integrated Slope Button: A 1.5° integrated slope button with a slight radius sits securely on pipe for fast, accurate 1/4" per foot drainage checks.
  • 22.5° & 45° Vials: Dedicated vials for common angles let you find 22.5° and 45° references quickly, speeding up layout and framing work.
  • Integrated B Tank Valve Key: A built-in B tank valve key opens an acetylene or B (or MC) tank valve without stripping the fitting.
  • Compact 9" Size: The 9" length fits easily in a tool pouch or pocket for quick access on plumbing, HVAC, and gas line jobs.

Irwin 1794153 – Frequently Asked Questions

1) Can the Irwin 1794153 torpedo level check 1/4 inch per foot drain slope on pipe?
That is exactly what the integrated slope button is for. The 250 Series level has a 1.5 degree slope button with a slight radius so it seats on round pipe instead of rocking, giving you a quick 1/4 inch per foot drainage read. Handy for DWV runs and condensate lines where you need to confirm fall without setting up a longer level.
2) Will a magnetic torpedo level hold itself on pipe and steel studs hands-free?
The Irwin 250 Series uses rare earth magnets rated 5x stronger than standard strip magnets, so it stays put on steel conduit, black iron, strut, and steel studs while you free both hands. It will not hold on copper, PVC, or aluminum, since those are non-magnetic. For PVC or copper runs you are holding it against the pipe, and the radiused slope button is what keeps it from rolling.
3) Which vials does the Irwin 1794153 have besides level and plumb?
Four reads total: level, plumb, 22.5 degrees, and 45 degrees. The plumb vial is a dual-sided Plumb Site design, so you can read it from either side of the level without craning around the tool, which matters when you are setting a riser against a wall. The 22.5 and 45 degree vials cover the common offset fitting angles in pipe work and the usual miter angles in framing.
4) Does the Irwin 250 Series level open an acetylene or B tank valve?
Yes. There is a B tank valve key built into the body, sized to open an acetylene or B (MC) tank valve without rounding off the stem. For an HVAC or refrigeration tech running a torch kit, that removes one loose key from the bag.
5) What is the Irwin 250 Series torpedo level body made of?
Die-cast aluminum. That is a step up from plastic-bodied torpedo levels for daily trade use, and it keeps the 9 inch tool light enough to carry all day. Aluminum also means it will not take a set the way a thin plastic frame can if it gets stepped on in a gang box.
6) Which Irwin part number do I order for the 250 Series magnetic torpedo level?
Order Irwin 1794153. That is the single model in this configuration, the 9 inch die-cast aluminum 250 Series magnetic torpedo level with the dual-sided plumb vial, slope button, and B tank key. There are no finish or length options to specify.
7) Is this torpedo level suitable for a plumbing and HVAC crew rather than just carpentry?
It is built around mechanical trades work. The slope button handles drainage pitch, the 22.5 and 45 degree vials match common offset fittings, the magnets grip black iron and steel strut, and the B tank valve key covers torch work. Framers get use out of the 45 degree vial and the magnets on steel studs, but the feature set is aimed at pipe and duct work.
