The Hollis 6-pin environmental seal cap socket is a professional, workshop-grade, specialized service tool engineered for dive technicians. Precision-machined from high-strength aluminium, it provides an exact interface for safely opening and closing the first-stage environmental seal assembly without causing damage to the component or surrounding regulator parts.
 
How It Works:
The tool features six precisely spaced pins that align and slot seamlessly into the matching layout of the Hollis first-stage environmental end cap (part # 27089). Equipped with an integrated 3/8-inch square drive, the socket attaches to standard workshop ratchet wrenches or torque wrenches. This allows the technician to apply controlled, even torque during assembly or disassembly, preventing tool slippage and ensuring components are not overtightened.
 
Key Features & Specifications:
Target Fitment: Explicitly designed to engage with the environmental seal end cap (part number 27089) used across Hollis regulator first stages.
Premium Material: Precision-machined from lightweight, heavy-duty aluminium for enhanced durability and tool longevity in commercial workshop environments.
Drive Interface: Features a built-in 3/8-inch square socket drive to accommodate standard mechanical tools and precise torque wrench attachment.
Component Protection: Engineered to distribute rotational forces equally across all 6 pins, eliminating localized pressure points and protecting the structural integrity of the cap.
