Designed to connect irregular lengths of stove pipe. The slip connector is adjustable from 4" to 18"L. ▪ Our connectors are made from premium 22 ga steel. ▪ Our pipes are welded, which gives them a much nicer appearance and ensure a sturdier assembly, unlike other 24 ga clip-on pipes. ▪ Our stove pipes come with a limited lifetime warranty to give you peace of mind.
