Standard vs Cross vs Special Selective Soldering Nozzles

Updated: August 10, 2026 · Author: SelectiveNozzle Technical Team

Direct Answer

Standard, Cross and Special describe three geometry groups in the SelectiveNozzle.com catalog. A Standard nozzle uses the regular catalog geometry, a Cross nozzle uses a cross-type working form, and a Special nozzle has a non-standard outline or dimensional relationship. The type is only one selection field. A buyer must still match the complete reference part number, ID/AD, height, base, engineering drawing and machine configuration.

Definitions

**Standard nozzle:** the regular wettable selective soldering nozzle geometry recorded for most catalog part numbers. Standard does not mean universal; two Standard nozzles can have different openings, heights and mounting bases.

**Cross nozzle:** a catalog nozzle whose working geometry is identified as Cross. The cross form can be used where the required solder contact pattern differs from a conventional circular opening. Cross products must be selected from their exact drawing, not by the word Cross alone.

**Special nozzle:** a part-number-specific geometry that does not fit the Standard or Cross group. Special records may use unusual ID/AD relationships, opening forms or heights. A Special label does not authorize dimensional substitution.

Step-by-Step Selection

1. **Record the full part number.** Preserve every letter, suffix and leading character. Alphanumeric references are case-insensitive in search, but the full reference must be included in the quotation.

2. **Check the type field.** Confirm whether the catalog record says Standard, Cross or Special. Do not infer type from a similar-looking image.

3. **Match ID/AD.** Compare the inner diameter and applicator diameter exactly. Use the [ID/AD overview](/selective-soldering-nozzles-by-id-ad-size) to find related records without treating them as interchangeable.

4. **Match height.** Read the overall height from the engineering drawing and compare it with the catalog height. Use the [height overview](/selective-soldering-nozzles-by-height) for alternatives.

5. **Confirm the base.** Distinguish the B14.1/B22 family from the B16.1/B36 family. A matching opening size does not compensate for an incompatible base.

6. **Compare the drawing.** Review the opening, body, shoulder and mounting geometry. For Cross and Special products, the drawing is especially important.

7. **Confirm the equipment configuration.** Equipment family names indicate compatibility context only. Final compatibility is confirmed during quotation.

Common Mistakes

  • Ordering by diameter while ignoring height and base.
  • Assuming every Standard nozzle is interchangeable.
  • Selecting a Cross nozzle from a thumbnail without checking the drawing.
  • Treating a Special nozzle as a custom blank that can be resized freely.
  • Shortening an alphanumeric part number or dropping its suffix.
  • Calling a Product Image a verified real photo. Product Images and engineering drawings remain separately labelled.

    If no catalog record matches, send a dimensioned drawing, clear old-nozzle photographs or a physical sample through the [Custom Nozzle request](/custom-nozzles). Include the machine configuration, required quantity and all critical dimensions. Availability, lead time and compatibility are confirmed in the quotation.

    Frequently Asked Questions

    Is a Standard nozzle universal?

    No. Standard identifies the geometry group, not universal compatibility. Match the part number, ID/AD, height, base and drawing.

    Can a Cross nozzle replace a Standard nozzle with the same ID/AD?

    Not without drawing and application confirmation. The working geometry differs even when one dimension matches.

    When should I request a custom nozzle?

    Request custom evaluation when no catalog part matches the required drawing, dimensions, base and equipment configuration.
