Purpose: Dustproof cap designed to protect your DIN level head from dust and debris, helping maintain regulator performance and reliability during dives and when gear is stored or transported. Material and durability: Precisionmachined from 6061 aluminum for corrosion resistance and longterm durability in marine environments. Featherweight design yet engineered to withstand accelerations up to 5g. Secure fit and specifications: Bulk dimensions 35 mm x 32 mm with a tooth gauge/thread of 5/814 NPS, ensuring a secure seal to prevent unwanted contaminants from entering the DIN connection. Color options: Available in Black, Red, Blue, Gold, and Silver so you can match or identify your gear quickly. Key benefits: Protects internal regulator components from dust, sand, and particulate contamination. Extends the service life and reliability of your DIN valve/head by reducing foreignmaterial ingress. Lightweight design adds negligible mass to your kit while providing robust protection. Compatibility and use: Fits DINstyle regulator valves or heads that accept a 5/814 NPS cap with the stated dimensions. Ideal for divers, dive shops, and technicians who need a reliable protective cap during transport, storage, or maintenance. Use scenarios: 1. Travel and transport: Cap your DIN valve before packing regulators in luggage or dive bags to keep dust and grit out during transit. 2. Offseason storage: Install the cap when storing your regulator for extended periods to prevent contamination and reduce maintenance needs. 3. Workshop and servicing: Use the cap during bench work or when regulators are placed on service shelves to keep openings clean between inspections. Practical notes: Verify your regulator accepts a 5/814 NPS threaded cap and matches the 35 mm x 32 mm envelope before . The aluminum construction balances corrosion resistance and light weight for dive use.
