Description
Techcon TSD1400-495A Buna O-Ring, .250 In. ID is a Techcon O-ring for maintaining compatible dispensing valves and fluid-control hardware. The listed size is .250 in. ID x .035 in. C.S., and the Buna compound should match the removed seal or the service documentation before the valve goes back into use.
Techcon O-ring Benefits
- Direct replacement part number helps purchasing and maintenance teams reorder the right seal.
- .250 in. ID x .035 in. C.S. sizing gives technicians a clear check against the removed O-ring before installation.
- Buna construction supports the valve service task when the equipment documentation calls for that material.
- The single-piece format suits one-for-one replacement when a bench does not need a full service pack.
- Small spare-part format stores easily with valve rods, seats, fittings, and other rebuild items.
Use this part during planned maintenance, troubleshooting, or repair when a valve shows wear at a seal location. Shut the equipment down, relieve pressure, clean the surrounding parts, and compare the old seal to the replacement before assembly. A correct O-ring helps the valve close consistently, but it should be installed only after the bore, stem, seat, and mating surfaces have been inspected for scratches, cured material, or debris.
Common Applications for Techcon O-ring
- Dispensing valve rebuilds and preventive maintenance work.
- Repair carts that stock small seals for adhesive, sealant, coating, grease, or paste stations.
- Replacement after cleaning, swelling, nicking, flattening, or routine service inspection.
- Maintenance programs that organize parts by Techcon number and seal dimension.
Compatible Service Notes
Match the SKU, material, and dimensions before installing this seal. Do not substitute by color or diameter alone, since similar O-rings may use different cross sections or compounds. Buna material is commonly selected for general dispensing equipment seal service where the removed part calls for the same compound. Keep new seals in clean packaging until the rebuild starts. During installation, avoid dragging the seal across sharp edges or dirty threads, and use the lubricant or assembly method specified by the equipment service procedure.
