Does your impulse sealer need a new heating element? This pack gives you 10 replacement heat strips, plus 10 pieces of PTFE (Teflon) cloth to go with them. Each strip is about 200mm long and 2mm wide (that's the standard 8-inch size). They're made from durable chromium alloy, which heats up fast, resists oxidation, and should last a good while. They're compatible with many 8-inch or model 200 sealers (like F-200, FS-200, PFS-200 models), but PLEASE double-check your machine's size before ordering - not all 8-inch sealers use the exact same part. Installation is usually pretty simple with just a screwdriver. If your old strip is discolored, cracked, or not sealing bags properly anymore, swapping in a fresh one can make your sealer work like new again. A super handy repair kit for anyone who uses an impulse sealer regularly for packaging.
