PRODUCT OVERVIEW

About this gear

L6X S40 P3403V Scuba Cylinder is an aluminium cylinder with 5.7 L water volume and a 207 bar service-pressure specification. Its listed dry weight is 7.2 kg.

Consider before buying

This version lists a M25 neck thread. Confirm the matching valve, Australian acceptance, inspection and local fill arrangements before purchase.

Our take

Choose the size around your equipment configuration and gas plan. We would compare handling, valve fit and refill support before choosing a brand. A higher pressure number alone is not a reason to change cylinders.

What still needs checking

Independent publisher ratings and exact-model photos remain separate research tasks; comparison scores are subjective editorial judgements.

We have not yet added independent review evidence for this entry. Manufacturer claims do not establish long-term reliability, value or a performance score.
