Miflex Xtreme LP regulator hoses are available in a range of colours letting divers “lead a more colourful life” and personalise their regulators as they require. Although 3/8″ UNF male thread is the standard size used for the majority of 1st stages, certain manufacturers us a hose with 1/2″ UNF thread. Please check your manufacturer’s information. We believe that these include: Mares: Abyss 22 series / Abyss 52 series / Prestige 22. Apeks: ATX 50 / ATX 100 / ATX 200. Custom lengths are no longer available.
