Purpose and benefit Dustproof protective cap that preserves DIN performance by keeping dust, sand, and debris out of your valve when diving, traveling, or storing gear. Protects sensitive threads and seals to reduce the risk of contamination and unplanned maintenance. Key features Material: Machined from 6061 aluminum for reliable corrosion resistance and longterm durability in aquatic environments. Lightweight: Weighs approximately 5 g, so it adds virtually no bulk or weight to your kit. Secure fit: Cap diameter 32 mm for a secure mounting over the valve area. Thread compatibility: Tooth gauge / thread dimensions 5/814 NPS to match DINstyle fittings. Fit: Designed to accommodate a 35 mm interface to prevent unwanted contaminants from entering the valve. Color options: Available in silver, black, red, blue, and gold to match or differentiate your gear. Why you need it Prevents grit and salt buildup that can impair valve performance and increase service frequency. Simple, lowcost way to extend the life of your regulators and maintain reliable DIN performance. Lightweight and compact so it stays on during travel or can be stowed in a pocket without adding bulk. Performance and durability Solid 6061 aluminum construction withstands the rigors of regular underwater use and outdoor handling. Machined fit and durable finish resist abrasion and maintain a secure seal against contaminants. Practical applications Scuba diving: Keep your DIN valve protected during shore entries in silty, sandy, or debrisprone conditions. Travel and storage: Protect regulator valves while packed in gear bags or transported between dive sites. Surface work and maintenance: Use the cap during boat transfers, rigging, or surface intervals to avoid accidental contamination.
