Overview
Palmetto Packings 1555 graphite filament packing is a severe service compression seal engineered for high-speed, high-temperature mechanical applications. The interwoven braided construction with pure 99% assay graphite filament impregnated with fine graphite particles provides reliable sealing on rotating and reciprocating shafts, pump stems, valves, and agitators. The solid lubricant coating eliminates wicking and fraying while maintaining a nearly zero coefficient of friction.
Key Features
- 99% assay pure graphite filament with integrated fine graphite particle impregnation
- Interwoven braided construction for strength and secure fit
- Solid lubricant to prevent wicking, fraying, and minimize frictional heat
- Effective heat dissipation keeps stuffing box cool and extends sleeve life
- Permits higher shaft speeds with lower leak-off and reduced pressure on packing
- Suitable for severe service and extreme temperature environments

Typical Applications
The Palmetto Packings 1555 is specified for rotating and reciprocating shaft seals, particularly in severe service environments where heat and speed demand superior performance. Common applications include:
- Centrifugal and rotary pumps
- Digestor and chemical pump stems
- Industrial agitators and mixers
- Valve stems and rotating equipment
- Oil & gas field operations
- Pulp & paper mill equipment
- High-speed machinery requiring heat dissipation
Compatibility & Replacements
Compatible With
- Standard pump and valve stuffing boxes rated for compression packing
- Rotating and reciprocating shaft seals (dynamic applications)
- Static seals in fixed or slow-moving applications (expansion joints, doors, valves)
- Equipment requiring RoHS and OSHA compliance
- High-temperature industrial systems up to 600°F continuous operation
Replaces / Drop-In Replacement For
Palmetto Packings 1555 is a direct replacement for equivalent graphite filament packing grades from other manufacturers where 99% pure graphite with solid lubricant coating is specified. Common cross-references include general-purpose graphite compression packing from Chesterton, John Crane, and other OEM suppliers. Verify exact size (square cross-section: 1/16″, 3/16″, 1/4″, 1/2″) and length with your system integrator before ordering.
Works With
- Standard packing removal and installation tools
- Conventional stuffing box configurations
- Mechanical seal backup systems
- Lantern ring or bearing ring support structures
- Shaft sleeves and pump internals rated for graphite contact
