What it replaces

Number	Maker	What it is
RP4993	Delta	Seats & Springs (2 ea) on Delta's product page. Its parts sheets list it as Seats & Springs, a separate number from the ball or stem above it.
RP1806	Delta	The seat alone. A distributor's 2000 Delta parts list shows RP1806MBS as a 24 pack of seats. One distributor lists two RP1806 seats inside RP4993.
RP3427	Delta	The spring alone. A distributor's 2000 Delta parts list shows RP3427MBS as a 24 pack of springs. One distributor lists two RP3427 springs inside RP4993.

Where it goes

Delta's sheet 70701 for single-handle kitchen faucets lists RP4993 with the RP70 ball for the 100, 103, 140, 141, 180, 300, 340, 400, 403, 440, 441, 480, D111 and D411 series. Delta's troubleshooting guide also names it for single-handle bath sink faucets.
Delta's two-handle sheets list it under the RP1740 stem for the 2100, 2102, 2400, 2402, 2174, 2176, 2474 and 2476 kitchen series and the 83200-SBS and 83500-SBS bath faucets, and under the RP25513 stem for the Classic 2500LF series centersets.
Delta staff on the RP4993 page say the parts work in any model that has seats and springs, and are not used with DST models or model 35955LF.
Danco says its 30300 pack, which it lists as replacing Delta #4993, fits Delta, Delex and Peerless single-handle faucets and Delta faucets made after 1976. No Delta document opened gives a year break.

Confirm it is your part

Replacement for Delta RP4993: the coil spring set under the black rubber seat — The spring set under the seat. Bench photo.

Look below the ball or stem. RP4993 is a seat resting on a coil spring, set in a hole in the valve body. Delta packs two seats and two springs.
Check the spring. It tapers. Delta says the wider end goes down into the valve and the seat sits over the narrow end.
Single-handle faucet: the pairs sit under a ball. Delta lists RP4993 with ball RP70 for lever handles and RP212 for knob handles.
Two-handle faucet: a seat and spring sit under each stem unit. Delta's sheets and troubleshooting guide show RP1740, RP25513 or RP24096 above them.
No seat and spring under the ball or stem means a different design. Delta says RP4993 is not used in DST models or model 35955LF.
Combo kits pack an old style set beside the new style. Jones Stephens calls the old style spring long and the new style spring conical. Delta's RP4993 spring has a wide end and a narrow end.

Look-alikes

Delta RP1806 seat and RP3427 spring

Why it gets confusedThey are the two pieces inside RP4993, sold under their own numbers and in 24 packs.

How to tellA distributor's 2000 Delta parts list shows RP1806MBS as 24 seats and RP3427MBS as 24 springs, each without the other. RP4993 is the seat and spring together.

Old style Delta seat and spring

Why it gets confusedCombo kits from Jones Stephens, BrassCraft, Danco (86968) and HD Supply pack old and new style sets in one card.

How to tellJones Stephens lists a long spring in its old style set and a conical spring in its new style set. Delta's RP4993 spring tapers from a wide end to a narrow end. Seat length is not a reliable tell; catalogs disagree on it.

Delta RP3614 single-handle repair kit

Why it gets confusedAnother Delta number for single-handle ball faucets that includes seats and springs.

How to tellA distributor's 2000 Delta parts list describes RP3614 as cam assemblies, O-rings, seats, springs and a wrench. RP4993 is the seats and springs only.

Delta stem units RP1740, RP25513, RP24096

Why it gets confusedNamed beside RP4993 on Delta's two-handle parts sheets and troubleshooting guide, and changed for the same spout drip.

How to tellThese are stems. RP4993 has no stem. Delta's sheets and troubleshooting guide change the seats and springs first and the stem unit only if the leak continues.

Pack count for the FourHome replacement. FourHome's own records give different counts, so this page states none. The listing states the contents.
Seat and spring sizes. Delta, distributors and FourHome's images give different figures, so none is printed.
Seat length and seat material of the Delta part. Catalogs disagree on both, so neither is printed.
Delta 1700, 1900 and 600 series and Touch2O models. No Delta document opened names them for RP4993, so none is listed. Tub spouts are not listed either: Delta staff answers on the RP4993 page disagree.
Danco 88103, Kissler PB4993 and BrassCraft SL0082 B as cross-references. No page opened names both the number and RP4993.

Field notes

Delta's single-handle kitchen sheet changes the RP70 ball together with RP4993 for a drip from the spout. Its two-handle sheets change RP4993 first and the stem unit only if the drip continues.

FourHome replacement
