Henry R. ★★★★★

Had to swap out the old seal on my gouging torch, and this O-ring restored the gas flow with a tight, leak-free fit. It's the exact replacement I needed, no modification required.

Natalie ★★★★★

Fits my machine torch perfectly and the seal is airtight—zero leaks since I swapped it in. The rubber feels dense and durable, not like some flimsy ones I've tried before. Just wish I'd ordered a few more to keep as spares.

Alexander V. ★★★★★

This little O-ring fit perfectly and stopped the tiny gas leak I was having on my torch head. It seats well and feels like a solid seal compared to the old one. Exactly what I needed for the replacement.
