Raypak replacement-parts documentation identifies the \u003cstrong\u003e950388F\u003c\/strong\u003e as the \u003cstrong\u003eTaco 1600-868CRP\u003c\/strong\u003e \u003cstrong\u003ewater seal kit\u003c\/strong\u003e, supplied with the \u003cstrong\u003emechanical shaft seal\u003c\/strong\u003e, a \u003cstrong\u003evolute\/casing gasket\u003c\/strong\u003e and an \u003cstrong\u003eimpeller bolt\u003c\/strong\u003e, so the wet end of the pump can be resealed in one service visit. The standard seal is built from a \u003cstrong\u003eceramic seat\u003c\/strong\u003e, a \u003cstrong\u003ecarbon face\u003c\/strong\u003e and \u003cstrong\u003eEPT (EPDM) elastomers\u003c\/strong\u003e, a combination that suits \u003cstrong\u003eheated water\u003c\/strong\u003e and \u003cstrong\u003eglycol-water\u003c\/strong\u003e hydronic loops.\u003c\/p\u003e\n\n\u003cp\u003eIn Taco's own replacement-parts list for \u003cstrong\u003ecartridge-design\u003c\/strong\u003e pumps, the \u003cstrong\u003e1600-868CRP\u003c\/strong\u003e is \u003cstrong\u003eItem #29\u003c\/strong\u003e, the \u003cstrong\u003e5\/8-inch shaft\u003c\/strong\u003e water seal kit for the \u003cstrong\u003eTaco 121 through 138\u003c\/strong\u003e pumps and the \u003cstrong\u003e1600 Series\u003c\/strong\u003e in-line circulators.

Taco lists a separate \u003cstrong\u003e1\/2-inch shaft\u003c\/strong\u003e seal kit, \u003cstrong\u003e1600-055RP\u003c\/strong\u003e, for its older-style pumps, so shaft size matters when ordering.

Before condemning the seal, rule out a leaking \u003cstrong\u003eflange gasket\u003c\/strong\u003e or fitting, then find out why it failed: \u003cstrong\u003eair in the loop\u003c\/strong\u003e, dry running, debris, \u003cstrong\u003eover-temperature\u003c\/strong\u003e or oil contamination will kill a new seal as fast as the old one. To install, isolate and drain the pump, pull the motor and \u003cstrong\u003ecartridge\u003c\/strong\u003e, remove the \u003cstrong\u003eleft-hand thread impeller bolt\u003c\/strong\u003e, and replace the seal and the \u003cstrong\u003evolute gasket\u003c\/strong\u003e. Keep the \u003cstrong\u003elapped seal faces\u003c\/strong\u003e clean and never touch them with bare fingers. Lubricate the elastomers with a water-compatible lubricant only, because petroleum grease attacks \u003cstrong\u003eEPT\u003c\/strong\u003e. Refill, bleed the air and check for leaks at operating temperature.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFactory Identified Kit:\u003c\/strong\u003e Listed by Raypak as the \u003cstrong\u003e950388F\u003c\/strong\u003e and cross-referenced to \u003cstrong\u003eTaco 1600-868CRP\u003c\/strong\u003e, so the correct \u003cstrong\u003eOEM seal kit\u003c\/strong\u003e is easy to confirm.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eComplete Reseal:\u003c\/strong\u003e Includes the \u003cstrong\u003emechanical seal\u003c\/strong\u003e, \u003cstrong\u003evolute\/casing gasket\u003c\/strong\u003e and \u003cstrong\u003eimpeller bolt\u003c\/strong\u003e to rebuild the \u003cstrong\u003ewet end\u003c\/strong\u003e without sourcing separate pieces.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHydronic Ready Materials:\u003c\/strong\u003e \u003cstrong\u003eCeramic\/carbon\/EPT\u003c\/strong\u003e construction handles \u003cstrong\u003ehot water\u003c\/strong\u003e and \u003cstrong\u003eglycol-water\u003c\/strong\u003e systems in \u003cstrong\u003eRaypak\u003c\/strong\u003e heating equipment.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eStops Shaft Leaks:\u003c\/strong\u003e Restores the \u003cstrong\u003eshaft seal\u003c\/strong\u003e and \u003cstrong\u003ecasing joint\u003c\/strong\u003e, protecting the \u003cstrong\u003emotor bearings\u003c\/strong\u003e and \u003cstrong\u003ebearing bracket\u003c\/strong\u003e from water damage.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIs the Raypak 950388F the same as the Taco 1600-868CRP?\u003c\/strong\u003e Yes.
