Y-strainer OEM replacement covers the requirements for y-strainer screens. Reproduced below: the complete specification table, the tolerance classes, and the companion and equivalent standards referenced when ordering to this document.
Y-strainer OEM replacement — Scope
Y-strainer OEM replacement specifies the designation system, dimensions and tolerances of y-strainer screens — mesh count or nominal opening, wire diameter and the permissible aperture deviations. Alloy chemistry, mechanical testing and delivery condition are governed by separate documents in the same standards family.
Tolerance Classes
Y-strainer OEM replacement defines tolerance limits on the average aperture and on the maximum single aperture, tightening as the aperture gets finer. For test-sieve duty the tighter ISO 3310-1 tolerances apply instead of the general cloth tolerances — specify sieve grade explicitly if the mesh will be used for particle-size analysis.
Specifications Defined by Y-strainer OEM replacement
| Nominal pipe size | Screen mesh | Material | Style | Reference standard |
|---|---|---|---|---|
| DN15 (1/2 in) | 20-Mesh | SS304 / SS316 | Cylindrical insert | Y-strainer replacement |
| DN25 (1 in) | 20-Mesh / 40-Mesh | SS304 / SS316 | Cylindrical insert | Y-strainer replacement |
| DN50 (2 in) | 20-Mesh / 40-Mesh | SS304 / SS316 | Cylindrical insert | Y-strainer replacement |
| DN80 (3 in) | 20-Mesh / 40-Mesh | SS304 / SS316 | Cylindrical insert | Y-strainer replacement |
| DN100 (4 in) | 10-Mesh to 40-Mesh | SS304 / SS316 | Cylindrical insert | Y-strainer replacement |
Equivalent Standards
Where direct equivalents exist (ISO ↔ ASTM ↔ DIN), they are listed on the parent Y-Strainer Screens page. Confirm against the specification table on this page — nominally equivalent documents can differ in tolerance limits.
When to Specify Y-strainer OEM replacement
Choose Y-strainer OEM replacement for international procurement and OEM supply where ISO documents are the contractual reference. It is the default modern specification for y-strainer screens.
