Replace Delta Faucet Stem: 7 Best Repair Kits Compared (2026)

By Caleb Morgan

Updated November 2026

If your Delta faucet drips from the spout or the handle feels stiff, the stem is often the culprit, and the fastest fix is to replace delta faucet stem parts rather than the whole faucet. The challenge is that Delta uses several stem families, and a kit that fits one two-handle model may not fit another. This guide compares seven repair kits built around the common RP-series stems, judged on how well they match Delta part numbers, what hardware is included, how cleanly the parts are described, and what owners commonly report after installation.

Buying Guide

Confirm your Delta stem family

Delta two-handle faucets commonly use RP-series parts such as RP24096, RP25513, RP4993 and RP24097. Look for the part numbers stamped on the old stem or in your faucet’s manual before buying. Bathroom sink and older Delta models may use different stems entirely.

Good picks for this: Repair Kit with RP24096 Cartridge, Danco 10405 Bathroom Stem

Decide between a single stem and a full kit

A single stem assembly is cheaper to manage, but a full kit that includes seats, springs and turn stops prevents a second repair if a small part is also worn. If you are unsure which part failed, a complete kit is often the more reliable choice.

Good picks for this: DELTA FAUCET RP25513 Stem Assembly, Repair Kit with RP24096 Cartridge

Check included hardware

Verify whether the kit includes rubber seats, compression springs and quarter-turn stops. Missing small parts are a common reason repairs stall halfway through. Count the pieces against the listing before installation.

Plan for quantity and spares

Single-set packages suit a one-time repair, while two-packs and eight-packs help if you maintain several faucets or expect repeat failures. Buying a spare set is often more useful than it sounds, since seats and springs wear at similar rates.

Good picks for this: RP24096 Cartridge Repair 2 Pack, RP25513 Faucet Stem Replacement 8 Pack

Compare parts against the original

Lay the new stem beside the old one and compare the stem shaft, the splines that hold the handle and the seat-seal shape. Mismatches here cause handles that slip or valves that do not seal. Take the old stem to a plumbing supply store if you are uncertain.

Consider build and material quality

Brass bodies and quality rubber seats resist wear better than bargain plastic components. Owners often report that seats are the first part to fail, so kits that include fresh seats and springs help reduce future leaks.

Good picks for this: 2-Pack RP25513 Faucet Stem Replacement Kit, Repair Kit with RP24096 Cartridge

Match the kit to the faucet type

Kitchen, tub and bathroom faucets from Delta can use different stems and cartridges. A two-handle kitchen or tub faucet typically needs RP-series parts, while some sink faucets need a different style. Confirm the faucet type before ordering to avoid returns.

FAQ

How do I know if my Delta faucet needs a new stem?

A stem is a common cause of a drip from the spout or a handle that feels loose, stiff or hard to turn. If the drip stops when you shut off the water supply, the stem or seats are likely involved. Compare the part number on the old stem before buying.

Can I replace a Delta stem without turning off the water?

No. Shut off the water supply under the sink or at the main valve, then open the faucet to drain remaining water before removing any parts. Closing the supply first prevents spraying and protects the work area.

Do I need the seats and springs when replacing the stem?

Often yes. Seats and springs wear alongside the stem, and replacing them during the same repair avoids a second disassembly. Many owners find that a complete kit is simpler than sourcing parts separately.

What is the difference between an RP25513 stem and an RP24096 cartridge?

The RP25513 is a stem assembly, while the RP24096 is part of the cartridge family used in certain Delta two-handle designs. Check your faucet’s manual or the part stamped on the existing component to confirm which one your faucet uses.

Will a Danco stem fit a Delta kitchen faucet?

The Danco 10405 is designed for Delta, Glacier Bay and Luxtra bathroom sink faucets rather than RP-series kitchen or tub models. Measure and compare the old stem before ordering, since a mismatch will not seal properly.

How long does a stem replacement usually take?

Most homeowners can complete a stem replacement in under an hour once the water is off and the parts are laid out. Allow extra time if corroded parts need to be loosened or if you need to order a missing component.

When should I call a professional?

If the faucet body is cracked, the water supply lines leak, or the part numbers do not match anything you can identify, consult a licensed plumber. Structural or supply-line problems can cause water damage if handled incorrectly.

Conclusion

For most two-handle Delta faucets, a complete repair kit with stem, seats, springs and turn stops is the most practical way to replace delta faucet stem parts in one visit. Choose the single RP25513 stem assembly if you have confirmed the stem alone is worn, and the Danco 10405 if your faucet is a bathroom sink style. Buyers managing several faucets or wanting spares should look at the two-pack and eight-pack options. Confirm your part numbers before ordering, since fit is the most common reason repairs fail.
