B14.1 vs B22 Selective Soldering Nozzles: What is the Difference?

One of the most common questions about Ersa selective soldering nozzles is the difference between B14.1 and B22 base types. This article explains the relationship between these designations and how to find the correct nozzle for your machine.

Key Takeaways

**B14.1 and B22 are physically identical** — same dimensions, same thread, same seating

**B14.1 is the legacy designation** — used in older Ersa catalogs and documentation

**B22 is the current designation** — used in newer Ersa part numbering systems

**No conversion needed** — any nozzle for B14.1/B22 fits both designations

**European notation B14,1 (comma)** — is the same as B14.1 (period)

B14.1 and B22 Are the Same Base Type

The short answer is: **B14.1 and B22 refer to the same physical solder pot base type.** They are not different sizes or different designs. The difference is purely in naming convention:

**B14.1** — The legacy designation used in older Ersa catalogs and documentation

**B22** — The current designation used in newer Ersa catalogs and part numbering systems

A nozzle marked as "B14.1/B22" is designed to fit both the legacy B14.1 solder pot and the current B22 solder pot, because they are physically identical. The thread pattern, seating geometry, and all critical dimensions are the same.

Why Two Different Designations?

Ersa updated its part numbering and naming system as the VERSAFLOW and ECOSELECT product lines evolved. The base type was renamed from B14.1 to B22 to align with a new catalog structure, but the physical dimensions, thread patterns, and seating geometry remained unchanged.

This is similar to how other Ersa designations were updated:

B16.1 became B36 (same physical base, new naming)

Some nozzle part numbers were reorganized under new reference systems

How This Affects Your Nozzle Search

When searching for replacement nozzles:

If your documentation references **B14.1**, search for both "B14.1" and "B22" — the same nozzle will appear under either designation

If your documentation references **B22**, the same nozzle fits — no conversion needed

Product pages on our site list both designations (e.g. "B14.1/B22") to ensure you find the right nozzle regardless of which naming convention your documentation uses

Verifying Your Nozzle Base Type

To confirm which base type your machine uses:

1. Check the machine model — VERSAFLOW, ECOSELECT and SMARTFLOW machines typically use B14.1/B22 or B16.1/B36 bases

2. Examine the solder pot — The base dimensions and thread pattern will confirm the type

3. Check your current nozzle — If it seats properly, the base type matches

4. Send us a photo — We can verify the base type from a clear photo of the nozzle and solder pot

Relationship to B16.1/B36

While B14.1/B22 is the most common base type, some Ersa machines use the B16.1/B36 base type (which follows the same legacy/current naming pattern). See our [B16.1 vs B36 Guide](/technical-guides/b16-1-vs-b36-selective-soldering-nozzles) for details on that base type.

**Important**: B14.1/B22 and B16.1/B36 are NOT interchangeable. They are different physical base sizes. You must use the nozzle designed for your specific base type.
