NH3 ACME Couplings | Secure every hookup, every time.

In NH3 application, speed and safety come down to your connections. Every time you move from a nurse tank to the toolbar, your ACME coupler has to deliver a tight seal: no cross-threads, no leaks, no wasted time. That’s why we stock ACME fittings and coupling nuts built specifically for anhydrous ammonia, so you can move from field to field without second-guessing your connections.

Frequently Asked Question

ACME couplers have coarse, heavy-duty threads that connect quickly and securely under high pressure. That makes them the safest and most efficient option for repeated NH3 hookups between nurse tanks and toolbars.

They reduce cross-threading, stripped threads, and leaks that can stop a rig in its tracks. A quality ACME coupling nut gives you confidence that every hookup is tight and safe.

Most NH3 toolbars and nurse tanks use standard ACME sizes, but it’s always smart to check your current fittings before ordering. If you’re unsure, our team can help confirm the right match. Contact us today.

If it’s in stock, we ship the same day. Most applicators receive their ACME fittings within a few business days, so they’re ready before tanks roll out. Visit our FAQs page for full shipping and returns information.
