The Ocean Reef SL35TX INT First Stage is CE certified and built for demanding scuba diving gear setups. Designed as a high-performance, balanced diaphragm first stage, it delivers smooth, reliable air delivery across a range of diving conditions and includes an anti-freeze kit for colder water environments.

Crafted for durability in saltwater environments, the chrome-plated brass body houses a stainless steel piston and a spring with a Teflon seat. An adjustable intermediate pressure lets divers fine-tune the breathing feel, while two high-pressure ports support versatile regulator configurations for scuba and diving gear systems.
