Cam and Groove Dust Cap 3in Type DC - Lightweight Aluminum Fitting

Our review of the 2PCS Cam and Groove Fitting Type DC focuses on practical workshop and industrial use. For anyone who needs a reliable, lightweight dust cap to seal male camlock hoses, this pair delivers straightforward performance: an aluminum body that resists corrosion, stainless steel cam arms for secure latching, and NBR seals that provide a dependable seal at common service pressures. The set includes two caps and two gaskets, making it a simple, cost-effective spare for maintenance kits or quick hose swaps.

Key Features

• Type DC Dust Cap: Designed to connect and seal to male camlock quick connect fittings to protect hose ends and keep contaminants out.
• Aluminum body: Light weight and corrosion and abrasion resistant, which reduces handling fatigue and stands up to routine field use.
• NBR (Buna-N) seal: Provides a reliable elastomeric seal that is suitable for general hydraulic and fluid transfer tasks.
• Stainless steel cam arms: Offer durable, rust-resistant clamping action that keeps the cap securely engaged under pressure.
• 250 PSI max pressure: Rated for typical liquid transfer applications, giving confidence for many industrial and agricultural jobs.

Who It's For

This fitting set is best for maintenance technicians, small contractors, and hobbyists who regularly couple and uncouple hoses and need a lightweight, durable dust cap to protect male camlock fittings during storage or transport. The included gaskets mean it is ready to use right away and useful as a spare set for service trucks.

Those who need specialized chemical compatibility, extremely high-pressure fittings, or non-metallic components for specific fluids should look at specialty seals or alternative materials; this aluminum/NBR construction is intended for general-purpose fluid handling rather than aggressive chemical service.

Pros & Cons

Pros

• Aluminum construction keeps the cap lightweight while providing corrosion and abrasion resistance for field use.
• Stainless steel cam arms ensure a secure mechanical connection and resist rust over time.
• Each kit includes two caps and two camlock gaskets, which is convenient for replacing worn seals.

Cons

• NBR (Buna-N) seals are general-purpose and may not suit all chemicals or extreme temperature ranges.

Specifications

Our Verdict

The 2PCS Type DC cam and groove dust caps are a pragmatic choice for routine hose maintenance and protection, offering a good balance of weight, corrosion resistance, and ready-to-use sealing with included gaskets. Buyers who need general-purpose, durable caps for liquid transfer systems will find solid value here; choose specialty seal materials only if your fluids or temperatures fall outside standard service ranges.
