Overview
The Garlock 29502-4107 is a KLOZURE® ISO-GARD® bearing isolator designed for high-performance pump and equipment protection. With a 1.750″ shaft diameter and 2.875″ bore diameter, this labyrinth seal uses glass-filled PTFE construction to deliver exceptional chemical resistance and durability across industrial applications. The non-contact design minimizes friction, reducing energy consumption while preventing shaft grooving and equipment damage.
Key Features
- IP 55 Ingress Protection: Tested to IEEE standard for water spray and dust exclusion
- Non-Contact Design: Eliminates friction on shaft, reduces energy consumption, and prevents shaft grooving
- Bi-Directional Labyrinth Seal: Prevents leakage of lubrication and contamination in both directions with single seal
- Glass-Filled PTFE Material: Excellent chemical resistance and long service life
- Drop-In Replacement: Designed to directly replace existing labyrinth seals on pumps without modification
