DIN 232 Adapter G1/4 Male UNDERSEA 1082

UNDERSEA Ltd, a Southampton-based manufacturer serving the diving industry since 1970, designs and produces high-pressure fittings to British and DIN standards. The 60-degree cone creates a metal-to-metal seal that withstands the repeated assembly and disassembly cycles typical of a busy dive operation.

Technical Specifications

• Manufacturer reference: 1082
• Inlet: Male DIN 232 bar — 5/8″ BSP thread, 5 turns, EN 144-3-2003 compliant
• Outlet: G1/4 male (¼″ BSP gas), 60-degree cone seat
• Material: chrome-plated brass
• Maximum working pressure: 232 bar (3,365 psi)
• Standard: DIN 477 — EN 144-3:2003
• Country of manufacture: United Kingdom (Southampton)
• Assembled to order — typical lead time: 2 to 3 working days
• High-pressure variant: 1082-HP (300 bar rated)

Applications

The 1082 is used in three main configurations across professional diving facilities. In nitrox blending panels, the 1082 provides a reliable 232-bar-rated connection within cascade or partial-pressure fill systems. In compressor manifold assemblies, it links G1/4 distribution outlets to individual DIN cylinders. The chrome-plated brass construction is compatible with clean dry air, standard nitrox blends (up to 40% O₂), and coastal salt-air environments.

Key Features

• Dedicated 232 bar geometry: the 5-thread DIN inlet fits only 232 bar cylinder valves — it cannot mate with 300 bar DIN valves, eliminating any risk of cross-connection between incompatible pressure ratings
• 60-degree metal cone seat: leak-free under cyclic loading without O-ring replacement — critical for dive centres connecting dozens of cylinders daily
• Chrome-plated brass: corrosion-resistant in salt air environments, suitable for permanent coastal dive centre installations
• Complementary 1082 family: 300-bar (1082-HP), NPT thread (1082-NPT), dual DIN (1082-SP), stainless (1082-SP-SS) for full fill station compatibility

Standards and Quality

The UNDERSEA 1082 is manufactured to DIN 477 and EN 144-3:2003, governing valves and fittings for self-contained breathing apparatus. UNDERSEA Ltd policy: “We only sell products designed to British or DIN Standards.” For oxygen-enriched service above 40% O₂, confirm material suitability with UNDERSEA before use. For UK cylinder valve standards and fill station guidance, refer to the British Sub-Aqua Club (BSAC).
