Description
Techcon Viton O-ring TSD1400-007BPK is a brown replacement O-ring for dispensing-equipment service. The Chemical Concepts listing and distributor data identify the size as 5/32 inch inside diameter by 1/16 inch cross-section, with the part supplied as a 10 pack for maintenance stock.
Techcon Viton O-ring applications
- Replacing worn O-rings in compatible Techcon dispensing assemblies.
- Restoring seal contact when leakage, swelling, flattening, or cracking appears.
- Keeping small seal spares grouped by part number for valve rebuild work.
- Supporting adhesive, sealant, coating, and fluid dispensing benches that need clean service parts.
Small O-rings are easy to mix up, so the part number and size should stay visible on the maintenance order. Installing a lookalike ring can create a leak, change valve feel, or shorten service life if the material is not correct for the fluid.
Techcon Viton O-ring handling notes
Remove the old ring without scratching the groove or sealing surface. Clean residue from the gland, inspect for nicks, and install the new ring without twisting it. Use only lubricants and cleaners approved for the equipment and the material being dispensed.
For purchasing, keep the dash size, material, color, and package quantity with the SKU. A 10 pack is useful when several valves are serviced in the same maintenance window or when one ring is damaged during removal. Store spare rings away from heat, sunlight, oil, and mixed hardware bins so the replacement stays clean and easy to identify. Use a separate labeled drawer so Viton and Buna rings are not mixed during a repair.
For related spares, fittings, and dispensing accessories, browse Chemical Concepts dispensers, mixers, and nozzles. Manufacturer information is available from Techcon.
