Parker's two-ferrule compression fitting, A-LOK® Series 1/4" NPT male connector tube fitting is designed to provide reliable leak-free connections for instrumentation, process and control, and analyzer applications that specify a two-ferrule tube fitting connection. The advantage of this tube fitting is Parker Suparcase® surface treatment technology which is an unique process that allows the 6Mo be hardened without affecting, and even increasing, the corrosion resistance of the material. Parker has been using the proprietary Suparcase® process to surface harden stainless steel ferrules for over 30 years. The process achieves a carbon supersaturated surface layer by altering the oxide passive layer on the surface of the stainless steel, without any detrimental effects.

Features / Benefits of Suparcase®
• Improved Hardness. Hardness Test – Suparcased samples are at least 250% harder than their untreated counterparts
• Increased Fatigue Strength Bending Test – Suparcased samples showed 50% increase in fatigue strength with respect to the same untreated samples under the same number of cycles
• No change in shape, size or colour
• Suparcase® Layer does not crack or delaminate during forming
• Abrasion and Erosion Resistance Wear Test performed on a high pressure homogenizer made out of Stainless Steel 316 – The Suparcase® samples increased the wear and erosion resistance by 13 times in air and by 10 times in seawater with respect to their untreated counterparts
• Exceptional Corrosion Resistance. ASTM G48 - Standard Test Methods for Pitting and Crevice Corrosion Resistance of Stainless Steels and Related Alloys by Use of Ferric Chloride Solution

Super Austenitic Stainless Steel 6Mo
6-Moly (6Mo) is a high performance alloy designed specifically for added corrosion resistance. It has the same structure as the common austenitic alloys, and greater levels of elements such as chromium, nickel, molybdenum, copper, and nitrogen, which gives it enhanced strength and corrosion resistance. 6Mo is especially suited for high-chloride environments such as brackish water, seawater, pulp mill bleach plants, and other high-chloride process streams. It is often used as a replacement in critical components where alloy 316/316L has failed by pitting, crevice attack, or chloride stress corrosion cracking. In many applications, the super austenitic stainless steels have been found to be a technically suitable and much more cost-effective alternative than nickel-base alloys. 6Mo is typically used in the following applications:

Applications:
• Instrumentation Hook-up Systems
• Offshore Control Panels
