Titan 9871105 O-Ring (Replaces 704-121) for AirCoat & Impact Systems

Titan 9871105 is an OEM siphon elbow o-ring that replaces the original Titan 704-121. This sealing component provides an air-tight seal at the siphon elbow connection on compatible AirCoat Air-Assisted Airless Sprayers, Impact, Advantage, RentSpray, and SprayTech systems.

OEM: Titan / SprayTech Part #: 9871105 (replaces 704-121) Type: O-Ring Use: Siphon Elbow Sealing
Detail Technical / Commercial Information
Product Overview Genuine Titan o-ring that provides an air-tight seal at the siphon elbow connection. This o-ring prevents air from entering the fluid line, ensuring the pump maintains proper suction and consistent material flow. It is a direct replacement for the original Titan 704-121.
Function Seals the connection between the siphon tube and the pump inlet, prevents air from being drawn into the fluid line, maintains proper suction pressure for consistent material pickup, and prevents fluid leaks at the connection point.
Industrial Applications Professional sprayer repair, suction system maintenance, o-ring replacement, and rental fleet equipment servicing.
Compatible Titan Machines SprayTech AirCoat, Titan AirCoat Air-Assisted, Impact 340/400/410/440/640, Advantage 400/500/600, RentSpray 400/600, SprayTech EP2005/EP2105/EP2205/EPX2155/EPX2255/EPX2305/EPX2355, Multi Finish Spray System 300.
Accurate Part Number 9871105 O-Ring (Replaces Titan 704-121). Used in pairs on suction systems.
Related Parts Commonly Serviced Together Siphon tube assembly, inlet filter (0295565), retaining clip (9822526), return hose assembly (0508614), and suction system components.
Common Problems Solved Loss of suction or difficulty priming, air bubbles in the fluid line, fluid leaks at the siphon elbow connection, and pump running but not picking up material.
Service Guidance Inspect the o-ring during routine maintenance or whenever the suction system is disassembled. Replace if it appears flattened, hardened, cracked, or shows signs of wear. Always replace o-rings when servicing the pump to ensure a proper seal. Loss of suction is commonly caused by worn O-rings allowing air to enter the fluid line.
Use with Coating Systems Supports AirCoat air-assisted airless sprayers and a wide range of Titan equipment for professional painting and industrial coating applications.
Commercial Benefits Restores proper suction and priming, prevents air leaks, ensures consistent material flow, and maintains reliable spray performance.

The 9871105 O-Ring (replaces Titan 704-121) is a critical sealing component that ensures proper suction and material flow in compatible spray systems. Installed at the siphon elbow connection, this o-ring prevents air from entering the fluid line, which is essential for maintaining consistent material pickup and spray performance. Over time, o-rings can become hardened, cracked, or compressed, leading to air leaks, loss of suction, difficulty priming, or fluid leaks. If you notice the pump running but not picking up material, air bubbles in the fluid line, or fluid seeping from the siphon elbow connection, inspect the o-ring and replace it if necessary.
