SEAC Regulators — Italian-Engineered, Cold-Water Certified
SEAC builds regulators with the same precision-machined approach the brand applies across its entire lineup — hot-forged first stages, balanced diaphragm designs, and exhaust geometry specifically engineered to keep water out and bubbles out of your field of view. Every component is made in Italy and individually tested before shipping.
At DiveCatalog.com, we carry the current SEAC regulator lineup as an authorized dealer: complete sets, octopuses, and replacement service kits.
The SEAC Regulator Range
IT500 — The Flagship Set
The IT500 brings together SEAC's most advanced regulator technologies in a single, properly matched set. An ergonomic knob integrated with the dive/pre-dive lever lets you adjust breathing effort and optimize the Venturi effect on the fly, eliminating the annoying free-flow that can occur when a regulator is left in the water unattended. The generously sized purge button, made from soft two-material PU, works smoothly even with thick gloves, while front and side openings reduce breathing effort and resist free-flow caused by strong currents. The Exhaust Deflector's unique geometry prevents water ingress through the exhaust valve even in strong side currents, while directing expelled bubbles to the sides of your face rather than across your field of vision — a genuinely thoughtful detail for anyone who's had bubbles obscure a shot or a view. The redesigned two-material LP hose guards prevent kinking while adding structure and comfort. The hot-forged, computer-machined first stage is a balanced diaphragm design with 2 high-pressure and 4 low-pressure ports, all ergonomically pre-oriented for whatever combination of second stage, octopus, gauge, BCD inflator, drysuit hose, and transmitter you're running. Available in DIN and INT (Yoke), EN250 A certified for cold water, with a matt chrome finish. The complete set ships in a semi-rigid preformed case with internal conformers for travel protection.
IT300 — Compact Octopus / Emergency Regulator
The IT300 is SEAC's lightweight, compact octopus, with a 1m braided lining hose for durability and flexibility and an adjustable Venturi effect switch for quick transitions between Dive and Pre-Dive modes. CE EN 250-2014 compliant and made in Italy, designed for dependable operation when every breath matters — exactly the moment an octopus is meant to perform.
Service Kits — X100, X200, Synchro
Genuine SEAC second-stage repair kits are available for the X100, X200, and Synchro regulator lines — each containing the specific O-rings, valves, pistons, and small hardware components needed for a proper rebuild, supporting long-term ownership of regulators already in service.

Frequently Asked Questions — SEAC Regulators
What is the Exhaust Deflector on the IT500?
A specifically engineered geometry around the second-stage exhaust valve that prevents water ingress even in strong side currents, while also redirecting expelled bubbles to the sides of your face rather than straight up across your field of vision — a meaningful comfort and visibility improvement.
Is the IT500 suitable for cold water?
Yes — it's EN250 A certified for cold water, the European standard specifically covering regulator performance in genuinely cold conditions.
How do I know which service kit my regulator needs?
Check the model designation printed on your second stage housing (X100, X200, Synchro, etc.) and match it to the corresponding service kit — each kit contains parts specific to that exact model's internal components.
What does DIN versus INT mean for the IT500?
DIN and INT (Yoke) refer to two different cylinder valve connection standards. DIN is more common in Europe and among technical divers; INT (Yoke) is more common in North American and Caribbean recreational diving. Choose based on what's standard where you typically dive, or contact us for advice.
