Black coating
The Black coating is an advanced blend of fluoropolymer, engineered plastics, and corrosion inhibitors that provides protection against rust and corrosion. Its properties include low friction, strong adhesion, and resistance to wear and abrasion, chipping, and elements such as weather, sunlight, and salt water. Laboratory and field tests show that the coating resists corrosion after more than 1,600 h of exposure, making it at least 300% more resistant than advanced plating. It works in a wide range of temperatures, from –420°F to 500°F. 

Stainless Steel O-ring Face Seals and Flange Adapters
A new addition to the company’s other stainless steel instrumentation fittings, these stainless steel O-ring face seals and flange adapters are able to endure extremely high working pressures. They have a high tensile strength and provide reliable corrosion resistance and sealing for critical, harsh-duty applications. Machined from round stock in connection sizes from ½ to 4 in., the flange adapters are bent into the desired angle using a hot-piercing technique, so they do not have braze or weld points. The flange adapters are designed to perform in limited-clearance applications. The O-ring face seal fittings, available in 23 different configurations and in 35 different size combinations, eliminate leaks in hydraulic systems, while permitting operating pressures as high as 6,000 psi.

Gap Gages
Gap Gages ensure that instrumentation tube fittings are sufficiently tightened. They are particularly useful for fittings in hard-to-reach locations and in systems where inadequate tightening could result in dangerous or expensive consequences. Once the instrumentation tube fitting has been installed, but prior to system pressurization, the Gap Gage is inserted between the fitting nut and the body hex. If the gage will not fit in at any point of the gap, the connection has been properly made up and no additional tightening is necessary. If the gage can be placed between the fitting nut and body hex, the assembly procedure must be repeated.

Presetting Tool
This presetting tool adjusts tubing ferrules prior to final assembly into a fitting. To use it, the installer first secures the tool in a vise, then removes the protective nut and assembles the fitting nut and ferrules loosely onto the tool. Then the tubing is inserted through the nut and ferrules until it settles in the bottom of the preset tool. After this, the tubing with the nut and ferrules can be removed from the body of the preset tool. Suitable for use in tight spaces and/or hard-to-reach areas, the tool is made from carbon steel and is available in sizes 0.625 in. and larger.

Instrumentation Fittings
These double-ferrule instrumentation-grade tube fittings provide leakproof and torque-free seals at tubing connections. This reduces the likelihood of hazardous and expensive leaks in instrumentation, process, pneumatic, hydraulic, gas and other tubing systems. The solid leak-free joint is formed as a five-piece connection comprised of the nut, the back ferrule, the front ferrule, the body and the tubing. The ferrules are tightly swaged around the tube, and the lack of initial strain on the tubing ensures against tubing wall damage. Axial movement along the tube prevents the transmission of torque from the fitting to the tubing. The fittings are resistant to temperature change and do not significantly reduce flow area. They can be remade several times and withstand heavy impulse and vibration in both vacuum and pressure systems. No special tools are needed for installation, which requires only 1.25 turns until the fitting is tight.
