Swivel-Attached Lanyard and Vented Cap — Replacement Accessory for First-Stage Regulators Key benefits Prevents lost or stuck caps: the swivel attachment lanyard keeps the protective cap secured to your first-stage regulator so you won’t misplace it between dives. Easier cap removal under pressure: the plug is vented to allow trapped high-pressure gas to escape, preventing the cap from sealing tightly and becoming difficult to remove. Built for the marine environment: lightweight, strong and saltwater-resistant so it performs reliably in dive conditions and resists corrosion and wear. Portable and simple to use: compact design and swivel attachment make installation and handling quick and practical during gear setup and transport. Function and compatibility Function: attaches the vented protective cap to the regulator first stage with a swivel fastening lanyard, preventing loss and simplifying removal when pressure is present. Compatibility: intended as an accessory or replacement part for underwater devices that use a first-stage regulator. Designed to work with standard first-stage regulator caps and similar protective plugs. Key attributes Attachment: swivel fastening lanyard for secure, flexible connection to the regulator. Cap design: vented plug to relieve high-pressure gas and avoid jamming. Performance: lightweight yet strong construction; resistant to saltwater exposure. Size and portability: compact for easy storage and transport (fits typical regulator cap applications). Use scenarios Pre-dive setup: secure the vented cap to your first-stage regulator on the boat or shore to keep the cap handy and avoid dropping it into the water while preparing gear. Surface intervals and travel: keep the cap attached during surface intervals or transit between sites so the cap is protected and always available when you stow or service your regulator. Maintenance and storage: use as a replacement accessory when storing or transporting equipment to prevent a sealed cap from becoming difficult to remove due to trapped pressure. Why choose this accessory Solves a common problem: prevents caps from becoming stuck because of trapped high-pressure gas and reduces the risk of losing small but essential protective parts. Practical and reliable: designed specifically for first-stage regulator applications with a vented cap and robust swivel lanyard to handle dive use and saltwater exposure. Note: Intended as a replacement or spare accessory for underwater devices with a first-stage regulator; check fit and compatibility with your regulator cap before purchase.
