Delta RP4993 Seats and Springs Application Guide
A focused identification record for Delta RP4993, emphasizing its documented application and the physical checks that distinguish it from similar service parts.
Direct answer
Delta RP4993 is a seat-and-spring kit documented for Delta two-handle faucets whose parts diagrams specify RP4993. The part number and the fixture's official service diagram are the fit authority; resemblance alone does not establish compatibility.

- Service scope
- One two-handle faucet
- Valve interface
- Installs beneath compatible stem units
- Identification
- Black elastomer seats paired with conical metal springs
- Application
- Delta lists RP4993 for many two-handle faucet diagrams
- Not included
- Stem units and handle hardware
What this record identifies
This page identifies Delta service part RP4993 as a seat-and-spring kit. Its documented relationship is Delta two-handle faucets whose parts diagrams specify RP4993; that is not a category-wide fit claim for every fixture carrying the brand.
A published part number is stronger evidence than color, silhouette, or a marketplace title. Begin with the fixture model and the manufacturer's exploded parts breakdown.
Interfaces and measurements that matter
For this application, record these physical facts before ordering: package: two rubber seats and two metal springs; service scope: one two-handle faucet; valve interface: installs beneath compatible stem units.
Measure a retained length from the same endpoints used in the manufacturer drawing. For a connector, compare both mating ends; for a seal, compare the installed groove or seat and not merely the loose component.
- Identification: Black elastomer seats paired with conical metal springs
- Application: Delta lists RP4993 for many two-handle faucet diagrams
- Not included: Stem units and handle hardware
Application evidence before purchase
Use the linked Delta source to confirm that RP4993 appears for the exact fixture or series. A source-backed model relationship outranks visual similarity to an uninstalled part.
If the fixture model cannot be recovered, preserve the old component's orientation and compare its markings, connection geometry, overall length where applicable, and every sealing surface. An unidentified look-alike remains unconfirmed.
Diagnosis and installation boundary
A matching brand does not make adjacent generations interchangeable. Hose couplings, stem lengths, diverter bodies, handle interfaces, and seal geometry can change while the exposed fixture remains similar.
Confirm that the leak or flow symptom originates at the mechanism this part services. Shut off the water, relieve pressure, protect the finish, and follow the fixture's service instructions before disassembly.
Questions
Before you remove or replace the part
Does RP4993 fit every Delta fixture?
No. Its documented relationship is Delta two-handle faucets whose parts diagrams specify RP4993. Confirm the exact model and service-diagram callout.
Is a visual match enough to order it?
No. Confirm the official part number and application, then compare the relevant connector, length, groove, or mating geometry.
What should be measured before purchase?
Use the application-specific facts: package, service scope, valve interface. Measure from the reference points used by the manufacturer.
