Valve stem packing stops fugitive
emissions
Measured leakage confirmed the packing meets the requirements of the most stringent US state air quality laws and consent decrees.
Garlock Sealing Technologies has successfully tested its Style 1303-FEP valve stem packing for compliance with the newly adopted API 622 Fugitive Emissions Standard Measured leakage confirmed the packing meets the requirements of the most stringent US state air quality laws and consent decrees

Gasketing material prevents failures
Multi-Swell creates its own load when it comes into contact with oil or water, virtually eliminating the most common cause of gasket failure - insufficient load.
Sealing system replaces mechanical seals
The Hydra-Justt sealing system avoids the risk of catastrophic failure in hostile, abrasive environments.
Yarmouth Laboratories, an independent testing facility in Yarmouth, Maine, conducted two iterations of the test.
The new API 622 standard reflects the unique operating environment in today's hydrocarbon processing facilities.
Using methane as the medium, the test subjected the Garlock Style 1303-FEP packing to three thermal cycles, from ambient to 260C and back again, simulating the real-world challenge of processing different grades of crude oil through the same equipment.
To model the minimum desired packing life in difficult refinery environments, Yarmouth Laboratories also conducted 1500 actuation cycles at 41 bar.
The five-ring Garlock Style 1303-FEP packing sets exhibited exceptionally low leakage rates, averaging just 41 and 53ppm by volume in the two iterations of the test.
Refineries can obtain engineered set performance from this fire- safe, spooled braided packing without the time and expense of having to measure the valves.
As such, it shortens turnaround windows by providing a more timely and cost-effective "build-in-place" repacking solution.
Additionally, 1303-FEP carries a five-year warranty, assuring continued compliance from turnaround-to-turnaround and eliminating the costs associated with on-line leak sealing, environmental penalties and valve replacement.
