Techcon 3300-0353 UHMWPE Cup Seal for TS7000 Auger Valves

Description

Techcon cup seal 3300-0353 is the current replacement path for the older TSD1399-3 seal listing. Techcon identifies 3300-0353 as a UHMWPE cup seal with stainless steel spring for TS7000 Series auger valves, giving maintenance teams a direct part number to use when the original seal reference points to the newer component.

Techcon cup seal applications

• Replacing the seal in TS7000 Series auger valve service work.
• Restoring valve performance when leakage, poor shutoff, or inconsistent deposits point to seal wear.
• Stocking a current 3300-0353 spare where older work orders still mention TSD1399-3.
• Supporting adhesive, sealant, paste, and process-fluid dispensing benches that use auger valves.

A worn cup seal can make operators chase a process problem that is really a maintenance problem. Replacing the correct seal helps bring the valve back to a known condition before changing air pressure, dispense time, or material setup.

Techcon cup seal service notes

Clean the valve cavity before installation and remove cured material, metal particles, or damaged seal fragments. Handle the UHMWPE sealing surface carefully and protect the spring from distortion. After assembly, run a short dispense test at normal settings and watch for leakage, delayed shutoff, and deposit variation.

For purchasing, reference 3300-0353 on new orders and note the older TSD1399-3 cross-reference in the maintenance file. That prevents a technician from ordering an obsolete seal description or a similar U-cup meant for another valve family. Keep the seal packaged until installation so the sealing edge stays clean and the spring is not bent in storage. This also gives purchasing a clean replacement trail when older part numbers appear on work orders.
