Description
Dispenser parts for Techcon assemblies include retaining rings that hold service components in position inside a bore or housing. This internal retaining ring is sized for a 1-3/8 inch bore with 0.050 inch thickness, giving maintenance teams a matched steel ring for repair work on dispensing hardware.
Dispenser parts fitment and use
An internal retaining ring seats in a groove inside a housing and keeps an adjacent part from moving out of position. In dispensing equipment, that retaining function may support a seal stack, bearing, piston-related component, or valve service assembly. Match this ring to the original groove diameter and thickness before ordering, since retaining rings are not forgiving when the bore size is wrong.
- Internal retaining ring for compatible Techcon service positions.
- 1-3/8 inch bore diameter fit.
- 0.050 inch thickness.
- Steel construction for mechanical retention inside dispensing assemblies.
Dispenser parts ordering notes
Install retaining rings with the proper pliers and inspect the groove before reassembly. A damaged groove, bent ring, or wrong thickness can let the retained component walk out under pressure or vibration. Related fasteners, seals, O-rings, and hardware are grouped in the dispensers, mixers, and nozzles category.
Retaining rings are small, but they carry a real mechanical job. Replace a distorted or sprung ring instead of reusing it during a rebuild, and keep spare rings labeled by bore size so maintenance teams do not mix close dimensions from different valve families. The correct ring should seat cleanly in the groove without forcing and should leave the retained component square in the housing.
