O-ring Face Seal Tube Fittings

Description

The Tube Fittings Division (TFD) of Parker Hannifin Corporationrecently expanded its Seal-Lok™ O-ring face seal tube fitting line in response to the vital push toward environmental sustainability.
 
Seal-Lok for compressed natural gas (CNG) provides reliable fuel conveyance in natural gas applications using an elastomeric seal compound specifically designed to address the needs of the market. The compound improves ozone resistance and supports wider temperature range requirements. It's also fully certified - NGV 3.1, ECER110 and ISO 15500 for on-vehicle CNG applications.
 
"Natural gas produces 30 percent fewer greenhouse gas emissions than gasoline or diesel fuel, making it an ideal alternative fuel for a diverse range of industry applications," said Ted Amling, Senior Project Engineer, Parker Hannifin Tube Fittings Division. "The Seal-Lok CNG O-ring face seal tube fittings have been the preferred fittings for CNG applications for several years. Now the recent seal enhancements will provide increased value and reliability."

Available in tube and hose sizes ranging from 1/4" to 3/4" (6 mm to 20 mm), Seal-Lok technology enhances the performance and reliability of O-Ring face seal SAE J1453 connections. The technology makes Seal-Lok for CNG ideal for high-vibration, on-vehicle applications where metal-to-metal sealing falters.
