Delta Packaging Copilot

Neck & Closure Compatibility Matcher

Pick a PET preform neck finish — get the exact compatible Delta PE closure(s), material and specs, then send an RFQ for the pair. Built from Delta El Nile's catalog compatibility rules.

Compatibility reflects Delta El Nile's catalogue; our engineering team confirms thread/seal fit and torque on every RFQ. PCO 1810 and 42/36 are preform necks with no standard Delta catalogue closure (see guidance).
