Best Torpedo Level for Pipefitters & Steamfitters

The Best Torpedo Level for Pipefitting Work

Plumb and level matter in pipefitting. A torpedo level is the tool you’ll use daily to check slopes, hangers, and vertical runs. The Empire EM81 10” magnetic torpedo level delivers solid accuracy at a price that makes sense, and it’s our pick for most pipefitters. If you demand premium German engineering and are willing to pay for it, the Stabila 70TMW is the professional-grade alternative that sets a higher standard.

Empire EM81 10” Magnetic Torpedo Level

The Empire EM81 is the working contractor’s level. It’s straightforward: 10 inches long, two vials for checking level and plumb, magnetic base for sticking to metal pipes and hangers, and honest enough accuracy for real-world pipefitting. The aluminum body is durable without being precious, and the vials are bright and easy to read from any angle in dim lighting.

The magnetic base on the EM81 is genuinely useful. When you’re checking if a hanger is plumb or if a copper line is setting correctly, the magnet locks it in place and frees both hands for what you’re actually trying to accomplish. It’s not so strong that you struggle to remove it, but it’s persistent enough that it won’t accidentally drop. For pipe work specifically, this magnet gets used constantly.

Accuracy-wise, the EM81 hits the mark for pipefitting standards. It won’t deceive you about plumb or level, and it won’t require constant recalibration. The vials are sealed and protected by the aluminum body, so you’re not constantly exposing glass to impact. The price point is where this tool really shines—at $15-25, you can afford to own two or three and not feel the weight of that investment.

The trade-offs are real but manageable. The vials themselves are simpler than premium levels, which means the reading is slightly less refined at extreme angles, though in practical pipe work that rarely matters. The aluminum body will eventually show cosmetic wear if you’re hard on tools, but that doesn’t affect function. And if you need sub-degree accuracy for precision work, you’ll want something better. But for everyday pipefitting? The Empire EM81 does the job.

Who should buy this: Every pipefitter should own at least one Empire EM81. The price is low enough that it’s an easy first purchase, and the quality is high enough that it’ll last years of heavy use. Apprentices, service techs, and residential plumbers especially benefit from the value. Also ideal for contractors who maintain multiple levels across different crews.

Stabila 70TMW Magnetic Torpedo Level

Stabila is a German precision instrument maker, and the 70TMW reflects that heritage. This is not a casual level—it’s built to exacting standards and priced accordingly. The vials are filled with a fluid that steadies the bubble and provides exceptionally clear readings. The magnetic base is precise and powerful without being aggressive. The overall feel is refined in a way that budget levels simply aren’t.

When you use the Stabila, you immediately sense the difference. The vials track smoothly, and the bubble settles faster. The accuracy is excellent—better than most job sites ever need, but welcome when you want certainty. If you’re setting precision hangers or checking long runs of pipe where small deviations compound, the Stabila gives you confidence.

The aluminum body is hard-anodized and resists cosmetic wear better than standard finishes. After a year of use, an Empire EM81 might show surface marks; a Stabila will still look nearly new. The magnet is strong enough to be genuinely useful but engineered so it doesn’t feel like you’re wrestling the tool off the pipe. Every detail is considered, and that thoughtful design adds up to a tool that feels premium in your hand.

The cost is the limiting factor. At $30-45, you’re paying roughly double what an Empire EM81 costs. For most pipefitting work, you won’t get measurably better results that justify that premium. The Stabila isn’t twice as good in practical use; it’s incrementally better in refinement and longevity. That’s a meaningful distinction—premium, not necessary.

Who should buy this: Professional pipefitters who work daily and appreciate quality tools, or those who do precision work where accuracy is critical. If you’re the type who maintains tools carefully and values the tactile experience of good engineering, the Stabila rewards that mindset. Master pipefitters and shop owners often prefer these. Also worth considering if you’re setting precision hangers or doing industrial work where tighter tolerances matter.

Our Recommendation

For the vast majority of pipefitters and steamfitters, the Empire EM81 is the right choice. It’s accurate, durable, magnetic, and affordable. You’ll get years of reliable service without hesitation about the purchase decision. Buy two or three if you work multiple job sites.

If you value precision tools and use this level constantly, the Stabila 70TMW is worth the investment. It won’t fundamentally change your work, but it will make the experience of using it more refined and eliminate any nagging doubt about accuracy.
