Autotrol (1040459) O-Ring Kit Piping Manifold / R&S 115-121AT / FDA EPDM Material

The Autotrol 1040459 O-Ring Kit delivers complete seal replacement for Autotrol piping manifolds and R&S 115-121AT control valves, engineered with FDA-approved EPDM material for reliable, food-safe water contact. This factory-spec kit includes one silicone tube and three precision o-rings sized to restore leak-free performance in residential and commercial water softener systems.
TECHNICAL DETAILS

What's Included

Manufacturer Part Number 1040459

AS568-115 Dimensions 7/8" OD × 11/16" ID × 3/32" CS (Danco #13 equivalent)
AS568-121 Dimensions 1-1/4" OD × 1-1/16" ID × 3/32" CS
Silicone Tube 1 included
Material FDA-approved EPDM rubber
Application Autotrol manifold and control valve sealing
COMPATIBILITY & APPLICATIONS

Designed For Autotrol Control Valves

This o-ring kit is engineered specifically for Autotrol piping manifolds and R&S model 115-121AT control valves found in residential and commercial water softening systems. The FDA EPDM material ensures compliance with potable water standards while delivering the chemical resistance and temperature tolerance required for continuous softener operation. Use this kit during routine valve maintenance, manifold rebuilds, or any time o-ring deterioration or leakage is detected at piping connections or internal valve seals.

💧 Replace all o-rings in the kit together rather than individually — mixed seal ages lead to uneven compression and premature failure at connection points.
