National 3A-B: a classic premix blowpipe hand torch (specs unconfirmed)

The National 3A-B is described as a classic blowpipe-style premix hand torch in National’s lineage — the kind of compact, hand-held burner historically common in scientific and entry-level soft-glass work. National is a long-running American hand-torch name whose branding and ownership have changed over time, so it’s best understood as a heritage lineage rather than a single modern product.

A note on confidence: we have only limited, unverified information on this specific model. Its existence is corroborated through dealer and secondary listings (it appears under the current Premier Industries name “3A-B,” and historically as the Veriflo/National “Type 3A” blowpipe), but the detailed specifications aren’t confirmed. We’re including the page for completeness rather than padding it with details we can’t stand behind.

What we can say

As a premix hand torch, fuel and oxygen mix inside the body before reaching the flame — a design that’s typically simple to light and predictable, which is part of why blowpipe hand torches became common teaching and laboratory tools. For how premix compares to surface-mix designs, see surface mix vs premix torches. As a hand torch, it’s held and maneuvered rather than bench-mounted, suiting assembly, spot heating, and mobile soft-glass work; the bench vs hand torch guide covers that distinction. If you’re still deciding what tool fits your work, start with how to choose a glass torch.

What we can’t confirm is the detail: jet count, oxygen flow (LPM), pricing, and the current maker behind any given example. Those are exactly the specifics to verify directly before buying.

Editor’s note: this entry is unverified. The 3A-B’s existence is corroborated through dealer and secondary listings, but its specifications — jet count, oxygen flow (LPM), pricing — are unconfirmed, and National’s lineage and ownership have changed over time. Confirm the exact product, maker, and specs with the seller before purchasing.
