Lord LP-50 10:1 Replacement Dispensing Plunger

Description

The Lord LP-50 plunger is a replacement piston for Lord’s 10:1 dual-cartridge dispensing systems, sized for the CPT cartridge pack used with Lord’s structural adhesives and sealants. It seats behind the resin and hardener chambers of the cartridge and drives both components forward at the correct 10:1 ratio as the dispensing gun trigger advances, so the mix ratio at the static mixer stays accurate from the first pull to the last.

When to Replace a Lord LP-50 Plunger

Shops running Lord two-part adhesives on a regular cycle keep spare plungers on hand because a worn or torn wiper seal on the old plunger lets material bypass and throws off the mix ratio at the nozzle. Swapping in a fresh replacement before that happens protects the bond line on whatever the adhesive is holding together, whether that is a fabricated metal assembly, a composite panel, or a vehicle repair.

Fitting the Lord LP-50 Plunger

Remove the spent cartridge from the dispensing gun, pull the old plunger free, and seat the new one squarely against the piston rod before loading the fresh CPT cartridge. A plunger seated at an angle can bind partway through the cartridge and stall the gun mid-dispense, so confirm it tracks straight before pulling the trigger. Keep a few spares in the tool crib, since a gun that stalls mid-cartridge wastes whatever adhesive was already committed to the mix nozzle.
