The all black chrome plated marine brass first stage regulator is a balanced diaphragm design which is environmentally sealed. The diaphragm membrane transmits the pressure changes to the internal mechanism eliminating the need for the surrounding water to enter the intricate mechanism. The benefit of this type of first stage design is that none of the internal parts are exposed to contaminants such as salt, sand, chlorine or pool acids. These environmental contaminants cause corrosion and mineral deposits to form on the internal mechanism deteriorating regulator performance.

Zeagle's conical precision stainless steel high-pressure valve and advanced polymer seat provide much greater reliability and service life compared to conventional designs, while improving responsiveness and Performance at all Breathing Rates. With high performance porting in a balanced diaphragm design with dry environment seal, makes this one clean regulator first stage that will give you years of corrosion free service. The F8 Regulator has an internal structure that allows for direct airflow through the 1st stage, providing outstanding performance. First Stage is equipped with 2 high pressure (HP) 7/16" threaded ports and 5 low pressure (LP) 3/8" threaded ports for mounting of gauges and additional accessory items such as inflator Hose and octopus regulator.

Zeagle's F8 Second Stage is lightweight, compact and comfortable, with diver adjustable resistance controls, free-flow control, and built-in anti-freezing features. Specific design changes have created a regulator that is resistant to free-flow on the surface, yet has incredible smoothness and ease of breathing underwater. This pneumatically balance downstream demand valve second stage regulator is manufactured from flexible thermoplastic, thermoplastic, elastomeric, polymer and silicone rubber. The F8 Second Stage has a new case design that is smaller, lighter and molded from high impact resistant materials than its predecessor. New case snap-in insert near mouthpiece allows you to personalize your F8 for color style. New front cover design with anti-surge and ha a new stylized Z" logo regulator second stage ha a new smaller mouthpiece with super soft silicone and color accented tear resistant Bite" lugs. New exhaust valve with improved dryness and lower exhalation effort. New inhalation effort control knob for better grip and style.

What else is new! The F8 has a new threaded cover ring for improved safety and new heat sink with improved materials and greater surface area to dissipate cold. New zirconium plated inlet tube for increased corrosion resistance, new inhalation diaphragm with improved response and tear strength and a newly redesigned poppet with improved tolerances. The F8 has a patented seat saving orifice, new low pressure second stage seat and a new second stage spring made from super alloy. The Standard Hose measures 30" (76 cm) and is 3/8" threaded. The complete regulator weighs approximately 2.56 lbs. (1,161 g) with the hose comes with a comprehensive owner's manual, and is Nitrox ready to 40% out of the box.
