Peerless faucet and shower part identification
A model-first guide to Peerless faucet cartridges, pressure-balance shower parts, and generation-specific repair records.
Direct answer
Find the Peerless model and its official parts diagram, then match the full repair-part number and original component instead of substituting a similar Delta-branded part.
Fit facts
What identifies this match
Use these details together. One matching feature does not establish compatibility.
- Company relationship
- Peerless is a brand of Delta Faucet Company
- Application rule
- Corporate relationship does not make every Delta and Peerless service part interchangeable
- Strongest clue
- The complete Peerless model and its official parts diagram
- Shower distinction
- Pressure-balancing shower components must match the installed valve and production generation
- Fixture distinction
- Single-handle, two-handle, kitchen, bath, and shower parts follow different records
- Fit evidence
- An official model-to-part relationship plus physical comparison
Locate the Peerless model
Search the installation sheet, packaging, receipt, product page, and labels under the sink. Retain the complete model and suffix when opening Peerless support information.
Read repair numbers exactly
Copy every prefix, digit, and suffix from the official parts diagram. A repair number may resemble a Delta identifier, but only a current application listing confirms that it belongs in the Peerless model.
Separate brand relationship from fit
Peerless and Delta share a company relationship and some support infrastructure. That fact is useful when locating documentation, but it is not evidence that any cartridge from one brand fits a fixture carrying the other name.
Check valve generation
Pressure-balance shower designs and faucet internals can change over time. Compare any production-date guidance, the installed valve, and the removed cartridge before using a current replacement.
Use fixture context
Determine whether the fixture is a single-handle kitchen faucet, two-handle lavatory faucet, tub-and-shower valve, or another layout. Note handle motion and hot or cold orientation before comparing stems.
Decision path
Identify the Peerless model, open its official maintenance or parts record, and capture the exact service number. Compare the removed component's function and geometry; if records conflict, ask Peerless support to confirm the model-specific replacement.

Questions
Before you remove or replace the part
Is Peerless made by Delta Faucet Company?
Peerless identifies itself as a Delta Faucet Company brand, but each part still requires a model-specific compatibility check.
Can I use a Delta cartridge in a Peerless faucet?
Only when official documentation lists that exact service part for the Peerless model; brand relationship alone is not proof.
How do I identify an older Peerless shower valve?
Combine the model or installation record, control behavior, production clues, and the removed cartridge, then confirm with Peerless support.
