RWO & Deckma Part Number
Cross-Reference Guide
Instantly cross-reference old to new part numbers for RWO and Deckma marine equipment
Finding the correct RWO or Deckma spare part can be challenging when part numbers change. This comprehensive cross-reference guide helps you identify current part numbers from old reference codes, Pos. numbers, or equipment models. With over 400 genuine parts cataloged, you can quickly find the exact component you need for your RWO oily water separator, sewage treatment plant, or Deckma bilge alarm system.
Quick Benefits:

How to Use This Part Number Reference/

Using Table 1: Old → New Part Number Cross-Reference
If you have an old RWO or Deckma part number from a previous order, nameplate, or manual:
Using Table 2: Search by Pos. Number & Equipment Model
If you know the Pos. number from equipment drawings or the specific equipment model:
Can't Find Your Part?
If your part number isn't listed or you need assistance identifying the correct component:

Table 1: Old Part Number to New Part Number Cross-Reference/

This table cross-references discontinued or superseded RWO and Deckma part numbers with current replacement part numbers. RWO and Deckma periodically update part numbering systems as equipment evolves. Use this reference to find the correct modern equivalent for legacy parts.
