700 Manual Piston, Rubber Lubricated, 3cc (Qty 50)

Description

This 700 Series manual piston is a rubber, factory-lubricated plunger sized for a 3cc syringe barrel. It seats inside the bore and rides forward under thumb or air pressure to push fluid out through the tip, and the lubricated rubber wiper maintains a low-friction seal against the wall through repeated strokes. Supplied in a 50-count pack, it matches the barrel diameter used across Techcon’s 700 Series manual and pneumatic dispensing platform.

Where this syringe barrel piston fits

Manual dispensing stations, bench assembly, and prototype work that load adhesive, grease, or thin sealant into a 3cc barrel need a piston that seals without binding on the stroke. This rubber lubricated piston suits low to medium viscosity fluids where a tight seal matters more than raw push force, since the lubricated rubber wiper conforms to minor bore variation better than a rigid piston can. Shops that hand-fill barrels for touch-up work, small-batch potting, or field repair kits use this piston style because it seals reliably on the first stroke without a break-in period.

Pressure rating for this syringe barrel piston

The rubber wiper’s lubrication reduces stick-slip during slow manual strokes, which keeps bead size consistent from the first shot to the last. Rated for the barrel’s standard 100 psi (6.9 bar) operating pressure, the piston holds a seal against most solvent-based and cyanoacrylate-compatible fluids without swelling or hardening in short-term storage.

Stock this piston with matching 3cc barrel bodies and stand-up tip caps so a hand-fill station stays ready between batches. Shops running several fluid types through the same barrel size often keep both the rubber lubricated piston and a white wiper piston on hand, since the rubber version favors sealing performance and the white wiper favors low-viscosity, tight-fit work. Browse syringe barrels and dispensing accessories for caps and tips sized to match. For the full piston and barrel lineup, see Techcon.
