Equipment guides

These guides apply the materials and chemistry framework from The Brewer's Manual to specific pieces of equipment — covering per-component material analysis, compatibility ratings, cleaning sequences, and known failure modes.

Each guide cross-references back to the relevant material pages in the materials register and to the wet-dry cycle model for the underlying reasoning.

Guides in this section​

  • Bucket fermenters — PPPP — Polypropylene A semi-crystalline polyolefin plastic widely used in fermenter buckets, lids, taps, and airlocks. Excellent chemical resistance across all homebrewing chemical environments. EU Regulation 10/2011 compliant. buckets, HDPEHDPE — High-Density Polyethylene A polyolefin plastic used in fermenter taps and spray bottles. Slightly better chemical barrier properties than PP. EU Regulation 10/2011 compliant. taps, grommets, and airlocks
  • FermZilla All Rounder (30 L) — PETPET — Polyethylene terephthalate The plastic used in the FermZilla All Rounder, Oxebar mini keg, and PET bottles. Recycling code ♻️1. Extensively tested for food contact with carbonated beverages. Do not exceed 40 °C when cleaning. pressure fermenter; LOW2 O-ring; GR-POKPOK — Polyketone An engineering thermoplastic used in current KegLand DuoTight push-fit fittings and the RAPT Pill body. Replaced POM due to POM's vulnerability to acid-catalysed degradation under WDC conditions. A-rated for all homebrewing chemicals.→ Full details components
  • Oxebar 4 L mini keg — multilayer PETPET — Polyethylene terephthalate The plastic used in the FermZilla All Rounder, Oxebar mini keg, and PET bottles. Recycling code ♻️1. Extensively tested for food contact with carbonated beverages. Do not exceed 40 °C when cleaning.; Santoprene elbow; CO₂ purge sanitisation
  • Bottles and bottling — PETPET — Polyethylene terephthalate The plastic used in the FermZilla All Rounder, Oxebar mini keg, and PET bottles. Recycling code ♻️1. Extensively tested for food contact with carbonated beverages. Do not exceed 40 °C when cleaning. and glass bottles; crown cap liners; oxygen management
  • Cornelius kegs and mini kegs — stainless steel; O-ring materials; pitting prevention
  • Serving systems — EVABarrier line; POKPOK — Polyketone An engineering thermoplastic used in current KegLand DuoTight push-fit fittings and the RAPT Pill body. Replaced POM due to POM's vulnerability to acid-catalysed degradation under WDC conditions. A-rated for all homebrewing chemicals.→ Full details DuoTight fittings; NukaTap
