Titan 814-004 Hex Nipple 3/8-inch NPT(M) x 3/8-inch NPT(M)
OEM Titan Fluid Fitting
Titan 814-004 Hex Nipple is an OEM 3/8" NPT male-to-male manifold fitting used to connect compatible high-pressure fluid components in gun manifold assemblies on PowrTwin, PowrLiner, PowrCoat, and Hydra sprayer models.
Compatibility Overview
Central hex section provides wrench engagement for secure tightening in confined manifold spaces. Creates a reliable male-to-male threaded connection between compatible female 3/8" NPT components. A worn or damaged nipple causes fluid leaks, pressure loss, and connection failure under high pressure. OEM replacement restores proper thread engagement and sealing.
Titan Fluid Fitting Replacement
Titan 814-004 Hex Nipple for Gun Manifold Assembly Service
Titan 814-004 is a genuine OEM hex nipple designed for high-pressure fluid-manifold and gun-manifold assemblies on compatible Titan airless sprayers. Listed as "Nipple, hex" in the official PowrTwin 6900/12000 Plus DI manual, the PowrTwin Plus DI manual, and the PowrTwin 3500 50th Anniversary manual, this precision fitting provides 3/8" NPT male threads at both ends with a central hex section for wrench engagement. The nipple creates a threaded male-to-male fluid connection between compatible female 3/8" NPT components. In Titan modular gun-manifold systems, it is used to connect manifold components and establish the high-pressure fluid path required when adding or connecting additional spray-gun outlets. It is documented for use across a wide range of Titan models including PowrTwin 12000/12000GH/12000GHD/12000XLT/12000XLTDI, 3500/3500-DC/3500 50th Anniversary, 4500, 4900/4900GH/4900XLT, 5500, 6900/6900GH/6900XLT, 8900/8900GH/8900XLT/8900XLTSP, PowrLiner 4955/6955/8955/6900XLT/8900/8900XLTSP/9900XLT, PowrCoat 730/745/940/960/975, and Hydra M2000/M4000. It is distinguished from the 814-002 nipple, which is used in corresponding 1/4-inch gun add-on arrangements. Always match the exact part number rather than selecting a nipple only by appearance. Over time, nipples can develop thread damage, corrosion, or wear that compromises their ability to seal properly. This genuine OEM replacement restores proper thread engagement, reliable sealing, and safe operation.

|---|---|
| Product Overview | OEM Titan hex nipple (3/8" NPT M × 3/8" NPT M) for high-pressure fluid-manifold and gun-manifold assemblies on compatible airless sprayers. |
| Function | Creates a threaded male-to-male fluid connection between compatible female 3/8" NPT components. Central hex section provides wrench engagement. Used to connect manifold components and establish high-pressure fluid paths in modular gun-manifold systems. |
| System Location | Gun manifold assemblies, fluid connection points. Listed in official PowrTwin 6900/12000 Plus DI, PowrTwin Plus DI, and PowrTwin 3500 50th Anniversary manuals. |
| Documented Compatible Models | PowrTwin 12000/12000GH/12000GHD/12000XLT/12000XLTDI, 3500/3500-DC/3500 50th Anniversary, 4500, 4900/4900GH/4900XLT, 5500, 6900/6900GH/6900XLT, 8900/8900GH/8900XLT/8900XLTSP; PowrLiner 4955/6955/8955/6900XLT/8900/8900XLTSP/9900XLT; PowrCoat 730/745/940/960/975; Hydra M2000/M4000. Verify your exact model against the parts diagram. |
| OEM Part Number | 814-004 Hex Nipple. Connection: 3/8-inch NPT male × 3/8-inch NPT male. Distinguished from 814-002 (1/4-inch configuration). |
| Common Problems Solved | Fluid leaks at manifold connections, pressure loss, thread damage from overtightening or cross-threading, corrosion, and connection failure under high pressure. |
| Replacement Indicators | Visible thread damage, corrosion, cracks, or persistent leaks at the connection that do not resolve with sealant or tightening. |
| Related Parts Commonly Serviced Together | Hex nipple (814-002), manifold block (970-100), high-pressure ball valve (941-555), hex nipple (808-555), pipe plug (227-033), outlet fitting (227-006). |
| Installation Notes | Apply appropriate thread sealant compatible with the materials being sprayed. Tighten securely using the hexagonal body. Do not overtighten. Inspect mating threads for damage before installation. |
The 814-004 Hex Nipple is a critical connector in gun manifold assemblies and high-pressure fluid systems. If you observe fluid leaks at a manifold connection, pressure loss, or visible thread damage, inspect the nipple and replace it if necessary. Always match the exact part number (814-004 for 3/8" configuration) against your Titan service manual or parts diagram, as manifold configurations vary across sprayer platforms.
