The 24127 Acetylene Nuts, LH Thread (2-Pack) are replacement left-hand thread nuts designed for securing acetylene hose connections in oxy-acetylene welding and cutting systems. Built for compatibility with standard acetylene fittings, these nuts help maintain secure, leak-resistant connections between hoses, regulators, and torch assemblies. The left-hand thread design follows industry standards for fuel gas connections, helping prevent accidental cross-connection with oxygen fittings. Supplied as a 2-pack, they’re a convenient solution for maintenance or repair—because a welding setup works a lot better when every connection stays tight and exactly where it belongs.
