17111 - ESAB CGA 510 Regulator Inlet Nipple .44-20M

Reliable Replacement Nipple for Acetylene & Propane Regulators

Keep your torch outfit running safely with the ESAB CGA 510 Inlet Nipple. If you've noticed a leak at your cylinder connection or if the seating surface of your current regulator nipple is scratched or dinged, it's time to swap it out. This part (17111) is designed specifically for fuel gas regulators that use the CGA 510 standard—commonly used for Acetylene, Propane, and other fuel gases. Don't risk a fire hazard or wasted gas; a fresh nipple ensures a tight, metal-to-metal seal against the cylinder valve.

This nipple features a .44-20M thread, which screws into the inlet port of compatible regulator bodies. It is made from durable, heavy-duty brass that stands up to the daily grind of the shop or job site. Installing this replacement part is a straightforward way to refurbish a regulator that has seen better days. Simply remove the old nipple (and nut), clean the threads, and install the new one to restore your equipment to factory-level performance. It’s a small investment that pays off in safety and peace of mind.

Welders and fabricators know that equipment downtime kills productivity. Having spare parts like this inlet nipple in your toolbox can save the day when a regulator gets dropped or a connection gets cross-threaded. Because it is an ESAB product, you can trust the machining quality and material strength. Whether you are setting up a new manifold or fixing an old Victor-style regulator, this nipple provides the secure connection you need to keep the flame burning steady.
