Product Description

IntroductionEG-LOK tube fittings are availablein a variety of materials，includingoptimized 316 stainless steel chemistrywith elevated ni ckel，chromium,andother elements for superior corrosionresistance in a variety of applications,including chemical processing,sour gas and subsea systems.EG-LOK continues to improve the performance and reliability of the tube fitting for use in thousands of diverse applications—including research,alternative fuels, analytical and process instrumentation, oil and gas, power,petrochemical, and semiconductor industries.

FeaturesTwin ferrule fittings provide metal-to-metal seal connections, non-elastomeric seals for leak-free connectionsEG-LOK twin ferrule fittings are designed to have a maximum allowable worxing pressure that is higher than that of any tubingIndustry standard design for all instrumentation grade tubingStainless steel tube harderness: the hardness of the tube shall be not greater than 85 HRBAvailable in sizes from 1/16 to 2in and 2 mm to 50 mmEG-LOK fittings materials include 316 stainless steel, steel, brass, aluminum, nickel-copper, Hastelloy C, 6Mo , Incoloy 625 and 825EG-LOK special treated back ferrule is to provide secureSilver coated threads to reduce gallingLeak-proof joints capable of satisfying high pressure vacuum and vibration applications

AdvantagesHydraulic proof pressure test (1.5 times the maximum permissible working pressure): no leakageDismantling and reassembly test (dismantle 10 times): no leakageMinimum hydrostatic pressure test (4 times the maximum permissible ambient pressure rating): no leakageVacuum test (1 x 10-4 mbar or greater): the leak rate less than 1 x 10-8Proven design, manufacturing excellence, and superior raw materials combine to ensure that every EG-LOK fitting meets our customers’ highest expectationsEG-LOK tube fittings deliver a leak-tight, gas-tight seal in an easy-to-install, disassemble, and reassemble form

The stainless steel EG-Lok compression wedge ring tube fittings are used in high-pressure and vacuum applications where the highest demands are placed on material and tightness. They are suitable for liquid and gaseous media. Also suitable for applications with gaseous hydrogen and certified to EC79 (EG-Lok).

Basically, the EG-Lok screw connection consists of 4 components or individual parts: The media-carrying base body (straight socket, elbow, T-piece or cross piece), the union nut and the two rings, also known as clamping and wedge rings.

The screw connections are used wherever gases and liquid media flow and where a high safety standard is required. It is also ideal for hydrogen applications.

The uEG2-Lok screw connections are mainly used:
