Bell & Gossett Mechanical Seals

PS-4349 Mechanical Seal — Bell & Gossett 1/2″

The PS-4349 mechanical seal is a direct-fit 1/2″ shaft seal for Bell & Gossett 2100 series pumps, cross-referenced to B&G P86261. It is built to OEM-equivalent standards or higher, and we supply it with an upgraded Silicon Carbide/Silicon Carbide face combination — a step up from the standard carbon version — for longer service life.

Upgraded Material 
The OEM seal (186046LF / 186047LF) uses an EPDM/Carbon/Silicon Carbide build. We supply the PS-4349 with an upgraded EPDM/Silicon Carbide/Silicon Carbide combination — both faces in hard silicon carbide — for better wear resistance and longer service life in demanding duty.
