Titan 235-026 O-Ring
OEM Titan Hydraulic Motor Seal
Titan 235-026 O-Ring is an OEM elastomer seal used in the hydraulic motor assembly of compatible PowrTwin, PowrLiner, and PowrTex sprayer models, providing leak-tight sealing between the valve sleeve, trip retainers, and cylinder head components.
Compatibility Overview
Prevents internal and external fluid leakage in the hydraulic motor circuit. A worn, flattened, or cracked O-ring causes pressure loss, erratic spray performance, and potential contamination ingress. OEM replacement restores proper sealing geometry and reliable operation.

Titan 235-026 O-Ring for PowrTwin, PowrLiner and PowrTex Sprayers
Titan 235-026 is an OEM O-ring that serves as a critical sealing component in the hydraulic motor assembly of professional Titan airless sprayers. Official Titan service manuals list this O-ring as item 19 in the hydraulic motor parts diagram, positioned between the piston and valve rod assembly. During reassembly, this O-ring must be well lubricated before the piston is installed onto the piston rod, and it works in conjunction with the piston seal (235-027) and piston retainer screw (235-022) to maintain a pressure-tight hydraulic motor. Verified compatibility data confirms this O-ring is used across an extensive range of models, including the PowrTwin 3500 through 12000 series, the PowrLiner 4000 through 8955 lineup, and PowrTex texture sprayers. Over time, O-rings naturally compress and take a set from pressure cycling, temperature changes, and chemical exposure. A worn, flattened, or damaged O-ring can lead to internal fluid bypass, pressure drop, sluggish pump performance, or external hydraulic fluid leaks. The 235-026 is manufactured to precise tolerances for reliable sealing against hydraulic fluid under high pressure. Always verify fitment against your specific model's parts diagram before ordering, as configurations can vary between model years and revisions.

When installing the 235-026 O-Ring, lubricate it well with hydraulic oil before installation. The O-ring is installed between the piston and valve rod assembly during hydraulic motor reassembly. Inspect the mating groove for nicks, corrosion, or debris that could damage the new O-ring. Do not use Piston Lube pump packing lubricant on hydraulic motor O-rings, as it is a solvent that will severely damage the seals. Always verify fitment against your specific model's parts diagram before ordering.
