The everyday pavé nozzle. 503 picks 1.3–1.4 mm rounds from the DSSMT-02 and SSMWT-02 trays (tray nos. 13-14) — the band that carries most commercial pavé work on an Indian floor. Because it runs the most hours, it is usually the first nozzle to need replacing. Stocked, same-day dispatch from Mumbai and Rajkot.

If your floor runs commercial pavé, the 503 is the nozzle that does most of your work. The 1.3–1.4 mm band carries the bangles, pendants and daily-wear rings that move in volume, which means this nozzle logs more hours per month than any other in the range — and wears accordingly. It pairs with the 13-14 zone of the DSSMT-02 and SSMWT-02 trays.
Being the busiest nozzle makes it the one most worth watching. Wear on a high-hours nozzle is gradual enough that a floor can normalise a two or three percent skip rate without ever deciding to accept it — the rework just quietly becomes part of the routine. Changing this nozzle on symptom rather than on failure is one of the cheapest quality decisions available to a production manager.

| Code | Nozzle | Stone Size | Pairs With Tray |
|---|---|---|---|
| SSMN-01 | 502 | 0.8 – 0.9 mm | DSSMT-01 / DSSMT-01L (tray nos. 08-09) |
| SSMN-02 | 502B | 1.0 – 1.2 mm | DSSMT-01 / DSSMT-01L (tray nos. 10-11-12) |
| SSMN-03 | 503 | 1.3 – 1.4 mm | DSSMT-02 / SSMWT-02 (tray nos. 13-14) ◀ this product |
| SSMN-04 | 503B | 1.5 – 1.9 mm | DSSMT-02 & DSSMT-03 / SSMWT-02 & SSMWT-03 |
| SSMN-05 | 504 | 2.0 – 3.0 mm | DSSMT-04 & DSSMT-05 / SSMWT-04 & SSMWT-05 |
The next nozzle up, 503B, covers 1.5–1.9 mm and reaches across two trays. Between the 503 and the 503B you have the whole 1.3–1.9 mm range covered with two parts.
A nozzle is the fastest-wearing part on a stone setting machine, and it rarely fails outright — it degrades. The tip aperture dulls, the sealing sleeve hardens, and your skip rate climbs a little each week until somebody finally notices that the wax models are coming off the bed with gaps in them. Watch for these:
On a high-hours nozzle, keep a spare and change on symptom. The part costs a fraction of one reworked piece, and on this band you are not reworking one piece — you are reworking whatever ran while nobody noticed.
Your skip rate tells you before anything else does. When a machine that used to run a full tray clean starts leaving occasional empty positions in the wax — and the tray, the air pressure and the stone size have not changed — the nozzle tip is what changed. Under a loupe you will usually see a dulled or slightly belled tip aperture, or a sealing sleeve that has hardened and stopped sealing.
Honestly, it depends on your hours, your stones and your air quality, so any number we quoted would be a guess dressed up as a spec. What we can tell you is what to watch: rising skip rate, inconsistent pickup on one head of a multi-head machine, and visible tip wear. Floors running continuous shifts treat nozzles as a stocked consumable, not a repair part.
Only within its published band. The tip aperture is sized to seal against a specific stone diameter — too small and it will not lift, too large and it loses vacuum around the girdle and drops the stone mid-travel. The ladder above shows exactly which band each nozzle covers.
On a multi-nozzle head, replacing them as a set keeps pickup consistent across positions — one fresh nozzle beside three worn ones just makes the worn ones obvious. If you are replacing one because it failed early, that is fine; if you are replacing on wear, do the set.
They are stocked. Nozzles ship same-day from our Mumbai and Rajkot warehouses because a nozzle you are waiting on is a machine that is not running. Keep a spare set on the shelf and you never make that call.
The SSMN-03 (503) ships same-day from our Mumbai and Rajkot warehouses, across India and to the 34+ countries we export to. Buying a full set across all five stone bands, or stocking spares for a multi-machine floor? Ask for set pricing rather than ordering them one at a time — and tell us how many nozzle positions your machine has so we send the right count.
Semsons Tech has supplied the Indian jewellery trade since 1978, with 16+ stores and warehouses, 450+ dealers and 40+ distributors behind every consumable we sell.
Not sure which part fits your machine? Send us your machine model and the stone size you are running, and we will confirm the correct item before we dispatch — so you never pay to find out it was the wrong one.
