NH3 Manifolds and ACME Dust Caps for Anhydrous Ammonia Systems

These Continental ammonia tank caps are commonly used on nurse tanks, applicators, and transfer hoses.

Continental NH3 Manifold – A-360MA-C-3A

A heavy-duty NH3 manifold is ideal for nurse tank and applicator transfer systems to distribute anhydrous ammonia safely and efficiently. 

Steel ACME Dust Caps For Anhydrous Ammonia

These anhydrous ammonia ACME dust caps protect NH3 fittings and valves from mud, grit, and corrosion between uses. Each cap includes a retention chain so it stays attached to the tank or hose and is always available during hookup.

• A-545-C – 3-1/4" ACME dust cap – For large nurse tank connections
• A-535-C – 2-1/4" ACME dust cap – Common ammonia transfer fittings
• A-529-C – 1-3/4" ACME dust cap – Smaller valves and applicator hoses

Nylon ACME Dust Cap – 22-63-FC – 1-3/4" ACME

A lightweight NH3 dust cap providing corrosion-resistant protection for anhydrous ammonia fittings. Ideal where a non-metal cap is preferred while still keeping dirt and moisture out of ammonia connections.

Prevent Leaks and Protect Ammonia Valves in the Field

• Keeps Dirt Out of Valves – Prevents contamination before hook-up
• Helps Prevent Leaks – Clean threads seal better and faster
• Protects Expensive Components – Avoids damaged valve faces and threads
• Speeds Up Hookups – Clean connections mean fewer delays
• Reduces Downtime – Reliable connections during peak application windows

During spring and fall application, a single bad seal can stop operations. Proper ammonia tank caps and maintained fittings help ensure the system connects right the first time.
