At a Glance: Brass nipple adaptor with 3/4 x 3/4 male/male threads for larger compressed-air connections.
The AirCraft SB1216 brass nipple is a robust adaptor designed to join two female-threaded pneumatic components with matching 3/4 x 3/4 thread sizes.
With male/male threads, it’s ideal for workshop air distribution, compressor plumbing, manifolds and higher-flow air system hardware where a strong, reliable threaded connection matters.
Brass construction offers durability and corrosion resistance, helping keep larger air line connections leak-resistant, service-friendly and dependable over time.
A strong male/male connector for main-line compressed-air plumbing
When you’re working with 3/4 fittings, you’re usually in the “main air line” territory—flow, reliability and leak control become very important. The SB1216 gives you a straightforward, sturdy join without unnecessary adaptors.
Extra Information
Confirm the thread type and sealing method used in your system before installation.
Use suitable thread sealant (PTFE tape or pneumatic thread sealant) where required by your application.
Start threads by hand to avoid cross-threading, then tighten evenly with the correct spanners.

On larger fittings, support the connected pipework while tightening—side-load on threads is a common cause of slow leaks over time.
