Description
The Techcon 460L-2 is a black rubber piston, one of the **dispensing valve parts** built for Techcon’s 400 series 60cc manual syringe barrel system. It seats inside the 60cc barrel and attaches to the matching plastic plunger rod, sealing against the barrel wall as the operator advances the rod by hand to push adhesive, sealant, or another viscous fluid out through the tip.
### Where these dispensing valve parts fit
* Pairs with the Techcon 60cc syringe barrel (400 series) and the matching plunger rod for hand dispensing of adhesives, sealants, and other viscous fluids
* Dual wiper blade design seals against the barrel bore so material moves forward without air bypassing the piston
* Silicone free and chloride free construction, suited to bonding and coating work where contamination control matters
* Non-lubricated version, for shops that prefer a dry piston over the lubricated 460L-2-LUB variant
* Rated for use in barrel systems operating up to 100 psi (6.9 bar)
A worn or hardened piston is one of the most common reasons a manual syringe barrel starts to skip or push unevenly. When the dual wiper blades lose their seal, air works past the piston face and the bead becomes inconsistent, especially on thicker fluids. Swapping the piston restores a clean seal without replacing the entire barrel and rod assembly, which keeps a bench dispensing station running at a fraction of the cost of a full syringe replacement. Shops that run several barrel sizes side by side often keep a small stock of pistons on hand so a worn one never stops a job mid-run.
### Dispensing valve parts specifications
* Material: black rubber
* Outer diameter: approximately 26.67 mm
* System: Techcon 400 series, 60cc manual syringe barrel
* Barrel system rated pressure: up to 100 psi (6.9 bar)
* Design: dual wiper blade piston, non-lubricated
Order the 460L-2 when a 60cc manual syringe barrel needs a fresh piston for continued hand dispensing. Techcon components are built to work with other Techcon parts in the same barrel and rod system, so pair this piston with the matching Techcon rod and barrel rather than a third-party substitute.
