Titan 930-937A Filter Cap Assembly for PowrTwin, PowrLiner and PowrTex Sprayers

Titan 930-937A is an OEM filter cap assembly that serves as the closure for the filter housing and incorporates a critical spring guide stem on compatible Titan and Speeflo sprayers. This cap threads onto the filter body to secure the filter element, gaskets, and O-ring, creating a pressure-tight seal. The cap features a long stem that acts as a spring guide and controls ball travel within the filter element, helping to reduce hydraulic shock at stroke changeover and minimize the opportunity for hydraulic stalls. Official Titan service manuals specify the filter cap as item 1 in the filter assembly diagram, with the spring (930-020) pushed onto the cap's spring guide until it snaps into place. Over time, filter caps can become damaged from overtightening, cross-threading, or corrosion, leading to fluid leaks, loss of filter sealing, and improper check ball function. The 930-937A is verified as compatible with an extensive range of models, including the PowrTwin 5500, 6900GH, 8900GH, 12000GH, and 12000GHD; PowrLiner 4000, 4900, 5000, 6000, 6900XLT, 8900, 8900XLTSP, and 9900XLT; and PowrTex 6900SF-12000SV. It is commonly serviced alongside the spring (930-020), filter element (930-006), PTFE gaskets, and O-ring. Always verify fitment against your specific model's parts diagram before ordering.

When servicing the 930-937A Filter Cap Assembly, inspect the spring guide stem for damage and ensure the spring (930-020) measures at least 3/4 inch uncompressed before reuse. Check the cap threads for cross-threading or damage. During reassembly, push the spring onto the guide rod until it snaps in place, then tighten the cap onto the filter body to engage the O-ring against the carbide seat. Always verify fitment against your specific model's parts diagram before ordering.
