Delta Ara T14067 Monitor 14 Cartridge: RP46074

The documented application

Delta identifies RP46074 for the Ara T14067 Monitor 14 Series valve trim on a compatible MultiChoice rough valve. That manufacturer relationship is the basis for this record; resemblance to another cartridge is not a fit claim.

Read the complete model or series designation. Trim number T14067 identifies a Monitor 14 application, but the concealed rough valve still must be checked before ordering a service cartridge.

Generation and control type come first

Establish whether the fixture is pressure-balanced Monitor 14 Series trim and whether its control is single handle controlling temperature and flow together. Those attributes separate parts that may share a brand and similar exterior trim.

Treat installation year as supporting evidence, not proof. A remodel can retain an older rough valve or pair newer-looking trim with an existing compatible valve body. The removed cartridge, model documentation, and valve identity are stronger evidence.

What to inspect before ordering

Turn off the appropriate water supplies before exposing a cartridge. Record the complete model number, all suffixes, the trim designation, and any markings on the removed cartridge without forcing the valve apart.

Compare those observations with Delta's current part page and the model-specific parts diagram. If the installed valve cannot be positively identified, use Delta's product-identification service rather than ordering from a photograph alone.

• Match the full model or Monitor series, not only the collection name.
• Confirm pressure-balance versus thermostatic operation on shower controls.
• Compare retained features, stem arrangement, and documented part number.

What this match does not establish

This record does not make RP46074 universal across Delta products. Finish, handle silhouette, escutcheon shape, and approximate cartridge dimensions cannot override a different model or valve generation.

It also does not show that a different cartridge should be modified to fit. A mismatch is a reason to stop and re-identify the fixture, especially when an older and newer Monitor valve can sit behind similar-looking trim.
