Description
The Techcon 20 oz cartridge is a high-density natural HDPE barrel that holds sealants, adhesives, and other fluids for air-powered or manual dispensing. It follows the common Semco-style format and ships 100 per case for shops that run steady volume.
Where the Techcon 20 oz cartridge is used
Aerospace, transportation, and general manufacturing fill these barrels with sealant or adhesive, then load them into a hand-held or bench air gun to lay controlled beads. The natural translucent wall lets an operator see remaining material and watch for air pockets before a shot. A 1/4 inch NPT female orifice accepts standard nozzles and retainers, so the cartridge drops into existing tooling.
How the Techcon 20 oz cartridge holds up
High-density polyethylene resists the solvents and chemistries common in industrial sealants while keeping the wall rigid under pressure. The barrel is rated to 100 psi maximum operating pressure, which matches typical shop air dispensing. Consistent molding keeps the bore and orifice uniform across the case, so retainers and pistons seat the same way every load. For light-sensitive or UV materials, the line also offers black and green wall colors. Buying the case keeps a filling operation supplied so a run is not interrupted to reorder empties. The smooth interior wall also helps a piston wipe clean, which reduces trapped material and waste at the end of each barrel.
