Description
The TS5540 Spray Valve Retaining Ring Kit replaces the dispensing valve parts that wear first inside a Techcon TS5540 series precision spray valve: the retaining rings and their backing washers. The kit supplies two retaining rings, two Mylar washers, and two general-purpose washers, along with fitting instructions, so a valve that has started to leak air or lose seating pressure at the nozzle can be rebuilt without replacing the full valve body.
Where these dispensing valve parts fit
TS5540 spray valves run thousands of open-close cycles per shift in automated coating, conformal coating, and light lubrication lines, and the retaining ring and its washer stack absorb that cycling first. Once a ring flattens or a Mylar washer compresses out of spec, the valve loses positive seating and starts to weep fluid or drift in spray pattern between cycles. Maintenance techs on fixed spray stations keep this kit on hand as a scheduled-maintenance item rather than waiting for a valve to fail mid-run, since the fix is a ring and washer swap rather than a full valve teardown.
Service life on these dispensing valve parts
The kit’s Mylar washers resist the compression set that causes a retaining ring to lose preload over repeated cycles, and the steel rings hold their shape through the valve’s rated 100 psi (6.9 bar) system pressure. Installation follows the included fitting instructions and typically takes a few minutes per valve with the spray valve already off the line.

Pair this kit with the TS5540 O-ring repair kit for a full seal refresh on the same maintenance pass, since both sets of hardware tend to reach end of service life around the same cycle count.
