Description
The Techcon Viton O-Ring is a fluoroelastomer seal measuring 0.489 inches inside diameter by 0.070 inches cross section, supplied in a pack of 10. It seats inside Techcon 700 Series barrel and accessory hardware to hold a tight seal between mating surfaces during pneumatic fluid dispensing.
Where the Techcon Viton O-Ring Fits
Viton (FKM) handles heat and aggressive chemistry better than standard nitrile, which makes this seal a good match for dispensing stations that run epoxies, cyanoacrylates, solvents, and reactive fluids. The seal keeps air pressure behind the material column and stops weeping at the joint, so shot size and bead consistency stay predictable across a shift.
- Inside diameter 0.489 in, cross section 0.070 in.
- Fluoroelastomer (Viton) compound for chemical and temperature resistance.
- Pack of 10 for planned reseal and maintenance work.
- Used in 700 Series syringe barrel and accessory assemblies.
- Replaces seals that have swollen, hardened, or taken a set.
Service Notes for the Techcon Viton O-Ring
Inspect the groove before fitting a new seal. Wipe out cured residue, check for nicks on the sealing face, and confirm the bore is clean and dry. Roll the seal into the groove without stretching it past its elastic range, and avoid sharp tools that can score the surface. Replace it whenever it shows flat spots, cracks, or chemical swelling so the air side stays leak free.
