Discuss requirement →02Type 4 HDPE-lined, glass-fibre reinforced cylinders in confirmed 13.7–47.8 L series.
View pressure pathway →Published composite values are nominal product-series data. Filling mass varies with LPG composition and permitted filling ratio; final tolerances, valve, markings and approval follow the confirmed order specification.
Confirmed composite range
Six water capacities across seven model configurations, with two casing sizes in the 26.2 L series.

A non-load-sharing HDPE liner provides gas containment, a fully wrapped glass-fibre composite shell carries the pressure load, and a protective polymer casing integrates the handle and stable base. The translucent pressure vessel allows an approximate LPG level check, subject to lighting and surface condition.
