Item #N/A

This Flint & Walling CJ101 repair kit puts the two parts that get replaced together on every reseal into one box — the rotary shaft seal and the stage gasket. Direct-fit replacement for Flint & Walling seal 131100 and gasket 130968 on CJ101 multi-stage high-pressure centrifugal pumps. Built to OEM-equivalent standards or higher.

Three kits available

Same kit, same fit — the difference is the seal inside it. Choose your build from the dropdown above.

Standard – Carbon/Ceramic/Nitrile — ordinary house water and pressure boosting
Upgrade – Carbon/Ceramic/Viton — hotter water, chlorine or chemicals
Premium – Silicon Carbide/Viton — sandy or gritty well water and hard-wearing duty

What’s included

800c mechanical seal (PS-800), 5/8 in. shaft — replaces Flint & Walling 131100, in your choice of material
Stage gasket, 4.5 x 7.062 in. — replaces Flint & Walling 130968, one supplied

This kit does not include the Flint & Walling 020240 square-cut O-ring.

How many gaskets does my pump need?

The CJ101 takes one stage gasket per stage. This kit includes one, so add extras to match your pump:

CJ101 2-stage — 2 gaskets in total: this kit plus 1 extra gasket
CJ101 3-stage — 3 gaskets in total: this kit plus 2 extra gaskets

Don’t replace just one gasket in a multi-stage pump — the others are the same age and will be the next thing to leak. Extra gaskets are linked below.

Which Kit Do I Need?

All three kits hold the same seal and the same gasket — the difference is what the seal faces and elastomers are made of. Find the water your pump handles and read across.

Kit	Faces / Elastomer	Max Temp	Choose This If
Standard – Carbon/Ceramic/Nitrile	CAR/CER/NIT	200°F	Clean house water, well water and pressure boosting at neutral pH. This is the standard build.
Upgrade – Carbon/Ceramic/Viton	CAR/CER/VIT	450°F	The pump runs hot, or the water carries chlorine, bleach or other chemicals that break down standard Nitrile.
Top gradePremium – Silicon Carbide/Viton	SIC/SIC/VIT	450°F	Sandy, silty or gritty well water, or any pump where the seal keeps wearing out early. Hardest faces we offer.
