Description
This Techcon TS6500 plunger cover protects the plunger assembly on the 20 oz cartridge mixer during the mixing cycle, keeping resin, adhesive, or hardener that weeps past the cartridge seal from reaching the plunger’s drive components. It is one of the dispensing valve parts that keeps a TS6500 mixer running clean between cartridge changes.
Where These Dispensing Valve Parts Are Used
The TS6500 Series mixes two-component adhesives and resins automatically, driving both plungers on a set stroke schedule while the fluid level sensor tracks the mix. Because the plungers and cartridge holder move under motor power during that cycle, this cover fits over the plunger head so any material that backs up around the cartridge outlet lands on the cover instead of working into the plunger mechanism. Shops running 20 oz two-part cartridges through the mixer daily replace the cover on a set schedule rather than waiting for a buildup to interfere with plunger travel.
Keeping the Mixer Running Clean
A fouled plunger slows the stroke speed and can throw off the fluid level sensing the TS6500 uses to set stroke length automatically, so a clean plunger cover is not a cosmetic part. The cover is sized to match the 20 oz cartridge holder and plunger diameter exactly, so it seats without a gap that would let material bypass it. Keeping a few of these dispensing valve parts in stock means a mixer does not sit idle waiting on a single worn cover.
