Titan 431-019A O-Ring/Backup Ring Set
OEM Titan Sealing Component
Titan 431-019A O-Ring/Backup Ring Set is an OEM-grade seal kit that replaces the older 431-019 part number, providing a high-pressure seal with backup ring support in the fluid section of compatible PowrTwin, PowrLiner, and PowrTex sprayer models.
Compatibility Overview
The backup ring prevents the O-ring from extruding into the sealing gap under high pressure, extending seal life and ensuring reliable operation. Replacing a worn set restores sealing integrity and prevents pressure loss or fluid leakage.

Titan 431-019A O-Ring/Backup Ring Set for Fluid Section Service
Titan 431-019A is an OEM-grade O-ring and backup ring set that replaces the older 431-019 part number. Designed for the fluid section and hydraulic systems of compatible PowrTwin, PowrLiner, and PowrTex sprayer models, this set creates a tight seal that withstands high pressure and temperature. The backup ring is a critical component that prevents the O-ring from extruding into the sealing gap under pressure, extending seal life and ensuring reliable operation. When the original O-ring hardens, flattens, or fails, pressure loss and fluid leakage occur. This replacement set restores sealing integrity and prevents costly downtime. The 431-019A is the current superseding part number for the original 431-019, ensuring compatibility with current production specifications.

| OEM Part Number | 431-019A O-Ring/Backup Ring Set. Replaces 431-019. |
| Common Problems Solved | Loss of system pressure, fluid leakage from the fluid section, visible O-ring wear or damage, inconsistent spray performance, and O-ring extrusion under high pressure. |
| Replacement Indicators | Pressure loss during operation, fluid leakage from the fluid section, visible wear or damage to the O-ring during inspection, or during routine fluid section service. |
| Related Parts Commonly Serviced Together | Other fluid section seals, packings, valves, and hydraulic motor components. Inspect all sealing surfaces during service. |
| Installation Notes | Follow the Pressure Relief Procedure before servicing. Lubricate the new O-ring before installation to prevent damage. Install the backup ring and O-ring in the documented position and order. Clean the sealing area thoroughly of all debris before reassembly. |
The 431-019A O-Ring/Backup Ring Set is a critical sealing component in the fluid section. Replace it whenever the fluid section is serviced or when pressure loss, fluid leakage, or visible seal damage is observed. Always lubricate the new O-ring before installation and ensure the backup ring is positioned correctly to prevent extrusion. Verify model compatibility against your Titan service manual, as seal configurations vary across sprayer platforms.
