This new system is reliable and compact, geared toward high-flow and low-to-medium system pressure applications. It is similar to the traditional Seal-Lok (SAE J1453) line, but can also adapt to the FlexFlange light-duty, flexible, corrugated-steel tubes used in gas appliances. The new system has shorter threads on the Lite ORFS end, and SAE-ORB-studded fittings use a light-duty port stud with shorter thread length. Fittings with male NPT threads use a light-duty version (PTF-Short). They also feature a hard-line (metallic tube) connection that uses existing stainless-steel Parflange tooling and equipment. Standard Seal-Lok Parflange sleeves are used throughout the traditional Seal-Lok and Lite fitting platforms. The systems allow high flow through the bore of the fitting, adapt to inch/metric tube, and tube and hose connections, and can be assembled by torque method. They are compact compared to instrumentation/hydraulic/traditional-grade fittings, use a captive O-ring groove seal for leak-free connection while retaining the O-ring and offer a zero-clearance fitting system for tight installations.
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
Airbus Defence and Space has 3D printed titanium brackets for communications satellites. The redesigned, one-piece 3D-printed brackets have better thermal resistance than conventionally manufactured parts, can be produced faster, cost 20% less, and save about 1 kg of weight per satellite.
A group of researchers at the Seoul National University have discovered a way to take material from cigarette butts and turn it into a carbon-based material that’s ideal for storing energy and creating a powerful supercapacitor.
