Armaflex EVO Refrigeration & AC Pipe Insulation Kit — Class O Nitrile Foam with 520 Adhesive, L414 Tape & Cable Ties

Armaflex EVO Refrigeration & AC Pipe Insulation Kit — Specified for Condensation Control

The correct kit for refrigeration engineers, air conditioning installers, and M&E contractors working on chilled water, refrigeration, and AC pipework. Armaflex EVO unslit tube is the industry-specified choice for these applications — the closed-cell nitrile foam construction provides the vapour resistance and condensation control that self-seal products cannot match on cold pipework.

Each kit includes unslit EVO insulation, Armaflex 520 contact adhesive for all joints and fittings, Armaflex L414 lagging tape, and cable ties — a complete, specification-correct installation package.

Every Kit Includes

• ✅ Armaflex EVO Pipe Insulation Lagging (Unslit) — Class O, Black Nitrile Foam, 2m lengths (your chosen pipe size and wall thickness)
• ✅ 1 × Armaflex 520 Contact Adhesive 500ml — the correct Armaflex-approved adhesive for all longitudinal seams, butt joints, tees, and bends
• ✅ 1 × Armaflex L414 Lagging Tape — the correct Armaflex-branded tape for sealing and finishing joints on EVO insulation
• ✅ 1 × Cable Zip Ties — Bag of 100 — for securing insulation on pipework runs

Why Unslit (Not Self Seal) for Refrigeration & AC?

• Condensation control requires a continuous vapour barrier — glued longitudinal seams with 520 adhesive provide a fully sealed joint that self-seal products cannot achieve on cold pipework
• Industry specification — refrigeration and AC engineers specify unslit Armaflex with 520 adhesive as standard; self-seal is not appropriate for sub-ambient applications
• Class O fire rated — compliant with UK Building Regulations and BS EN 13501
• Closed-cell nitrile foam — zero water vapour transmission when correctly installed; prevents condensation, corrosion, and energy loss on chilled pipework

Choosing Your Kit Size

Select the pipe outside diameter (OD) and insulation wall thickness to match your specification or design brief, then choose your run length (2m, 4m, 6m, or 10m). For condensation control on chilled water systems, 19mm or 25mm wall thickness is typically specified — check your design brief or contact our technical team for advice.
