Every Delta El Nile reference is a readable code, not a random number. Once you know the four parts, you can tell a preform’s application, weight and neck at a glance — and write a precise line on your RFQ. Here is how to read it.
The pattern
Preform SKUs follow DEN-[APPLICATION]-[WEIGHT]-[NECK]. For example DEN-CSD-13-PCO1881 is a 13 g carbonated-soft-drink preform on a PCO 1881 neck.
Part by part
- DEN — Delta El Nile for Industry, the maker prefix on every reference.
- Application — the market family:
CSD(carbonated soft drinks),WATER,JUICE(juice & dairy) orOIL(edible oil). Closures useCLO. - Weight — net preform weight in grams. An underscore stands in for the decimal point, so
18_5means 18.5 g. - Neck — the thread standard:
PCO1881,PCO1810,2925,3315,38MMand so on. This is the part that must match your cap and your filler.
Closures read slightly differently
Closure codes start DEN-CLO- followed by the neck and a descriptor — e.g. DEN-CLO-29_25_WATER (a 29/25 water cap), DEN-CLO-32_15 (a 32/15 juice/dairy cap) or DEN-CLO-48MM_HANDLE (a 48 mm cap with handle). The neck in the closure code is what pairs it to the matching preform.
Why it matters on an RFQ
Quoting the full SKU removes ambiguity — application, weight and neck are all fixed in one string, so there is no “which 15 g CSD preform?” back-and-forth. If you do not have the code yet, filter by application, weight and neck in the Product Finder to land on the exact reference, cross-check the neck against your cap with the neck-finish guide, and drop the SKU straight into the Smart RFQ Builder.
