Palmetto Products, 631A-13890657, 1389 Series 100% GFO Expanded PTFE with Graphite Compression Packing Seal, 1/4″ x 5′
Features:
- Palmetto style 1389, (100% GFO®) delivers the best all-around packing on the market.
- Heavy graphite loading serves to both increase the heat transfer rate and decreases thermal expansion.
- This permits higher shaft speeds with less risk of glazing or burning.
- This reduces break-in time, lowers the chance of scoring, and promotes cooler long-term running.
Applications:
- Style 1389, (100% GFO) is highly recommended in wide-ranging service conditions, including highly reactive fluids, high shaft speeds and moderate to high pressures.
- It is proven in such diverse equipment as rotating pumps, valves, mixers, blenders, extruders, reciprocating pumps and agitators, among others.
