Zeagle F8 Regulator 1st & 2nd Stage Set - REG176 DIN
Zeagle’s flagship regulator. Environmentally and dry sealed.
The Zeagle F8 first stage, complemented with a flagship 2nd stage, is one of the best performing diaphragm regulators on the market today.
When building the F8 Regulator, we partnered with Atomic Aquatics and engineered over 20 improvements on everything from inner mechanisms and materials to exterior controls and aesthetics.
What’s the result? The F8 breathes better, works harder and lasts longer than any other regulator we’ve ever made. Our conical precision high-pressure valve provides greater reliability and service life compared to conventional designs, while improving responsiveness and performance at all breathing rates.
Features
- First stage has a dry-sealed spring chamber to stop freezing at water temps below 40 degrees F
- First stage is coated with flat black chrome plating in order to protect the brass from corroding. A very durable black PVD is used to coat the high use port plugs, to protect from wear and tear and corrosion
- Personalize your F8 for color style with a color kit
- Front cover design with anti-surge and new stylized “Z” logo
- Smaller mouthpiece with super soft silicone and color accented tear resistant “Bite” lugs
- Exhaust valve with improved dryness and lower exhalation effort
- Inhalation effort control knob for better grip and style
- Threaded covering for improved safety
- Heat sink with improved materials and greater surface area to dissipate cold
- Zirconium-plated inlet tube for increased corrosion resistance
- Inhalation diaphragm with improved response and tear strength
- Redesigned front cover and inhalation effort control knob use co-molded components that provide grippy ease of use
- Co-molded silicone mouthpiece for better fit and less jaw fatigue
- Redesigned poppet with improved tolerances
- Patented seat saving orifice
- Low pressure 2nd stage seat
- 2nd stage spring made from super alloy
- Made in the USA — Berry Compliant

Q&A
Q: What is the Zeagle F8 Regulator 1st & 2nd Stage Set (REG176 DIN)?
A: A premium, high‑performance scuba diving regulator set with a DIN first stage and matched F8 second stage — engineered for smooth breathing, reliability, and corrosion resistance.
Q: Who should use this regulator set?
A: Recreational to advanced divers seeking a durable, dependable primary regulator — ideal for regular open‑water and Nitrox diving.
Q: What are the key performance features?
A: Balanced diaphragm first stage with environmental dry seal to prevent freeze and corrosion; high‑pressure precision valve for consistent performance at all breathing rates; adjustable second stage with low breathing effort.
Q: How does it perform in cold or harsh conditions?
A: Dry sealing and heat sink design enhance cold‑water performance, while corrosion‑resistant coatings and zirconium‑plated inlet tube improve longevity.
Q: What comfort features does it offer?
A: Smaller, super‑soft silicone mouthpiece reduces jaw fatigue; inhalation effort control knob allows fine tuning of breathing resistance.
Q: Is it compatible with Nitrox?
A: Yes — the F8 regulator platform is typically Nitrox‑ready, allowing safe use with enriched air mixtures up to ~40% O₂.
Q: Why choose the DIN configuration?
A: DIN (screw‑in) connection provides a more secure seal at high pressures and reduces the risk of regulator detachment compared to yoke in demanding dives.
Q: What’s included in the package?
A: DIN first stage with multiple HP/LP ports and matched F8 second stage regulator — ready for installation and dive use.
Maintenance Tips
-
Rinse first and second stages with fresh water to remove salt, sand & chlorine; avoid long submersion and don’t depress the purge during rinsing.
-
Shake or blow out excess water from the second stage before drying.
-
Reattach the dust cap to protect the DIN inlet and internal ports before storage.
Cleaning & Inspection
-
Wipe mouthpiece, hoses & exterior with mild soap and fresh water; dry completely.
-
Check for air leaks, cracks, worn O‑rings, hose kinks, corrosion or damage.
Lubrication
Storage
-
Air‑dry fully in a cool, shaded area; store away from direct sunlight, heat, or humidity.
-
Do not store with high pressure on the tan
