- Compatibility: 6L hose holder fits 6L bottles; the 12L hose holder fits 11–12L bottles, ensuring proper sizing for common cylinder options. - Durable in diving environments: designed to withstand time and the harsh diving environment; resistant to temperature changes, salt, and chlorine. - Elasticity and grip: maintains its elasticity at very high and very low temperatures and prevents slipping on the cylinder when storing or unfolding the hose. - Material quality: made of high quality, highly elastic rubber to securely secure immersion oxygen bottles. - Practical use: keeps hoses organized and secured during storage, transport, and on-site setup for immersion oxygen bottles. Use scenarios: - In dive shops, boats, or storage rooms, attach to 6L or 11–12L bottles to keep hoses neatly secured during idle periods and transport. - On-field dives or training sessions, quickly secure and release hoses without slippage when preparing gear or packing up. - In clinics or dive centers during maintenance, use to organize hose routing and prevent accidental tangling or damage during servicing.
