Overview
The SEPCO DFR-PM3-HEAD 280864 packing ring set consists of three compression packing rings engineered for use in pump casings, valve bodies, and other rotating equipment requiring reliable shaft sealing. Compression packing employs a gland to tighten the top packing ring, compressing it onto the stuffing box. These packings are typically made of soft materials and inserted as cut rings between the rotating member and the pump casing. This product represents the industrial-grade fluid sealing technology that SEPCO manufactures for process industries and heavy equipment applications.
Key Features
- PTFE-treated packing fibers protect against chemical attack and reduce friction at the shaft interface
- PTFE-treated SEPCO packing runs cooler, lasts longer, and allows controlled gland adjustment across the full service life without shaft damage
- Set of three rings — ready for installation in standard stuffing box configurations
- One of the most reliable and cost-effective shaft sealing methods available, particularly for applications where controlled leakage is acceptable
- Designed for use in pumps, valves, and other industrial rotating equipment
