Tylok b-4-dme-4 Dme 90 Deg Male Elbow 1/4 in Brass

Product Description

The TYLOK b-4-dme-4 is a 90-degree double ferrule male elbow tube fitting in the DME series, manufactured from brass bar stock and forging stock meeting ASTM B16 Alloy 360 and ASTM B124 Alloy 377 standards. It connects 1/4-inch tubing to a male NPT threaded port, making a right-angle transition in instrumentation and process tubing lines. The double ferrule design provides a robust mechanical grip and reliable seal without the need for flaring or brazing. Weighing 0.13 pounds, this fitting is compact and suited for high-integrity tube connections in tight quarters. It is manufactured domestically in the United States under ISO 9001:2008 quality control standards.

This fitting is used in instrumentation, process control, pneumatic, and hydraulic tubing systems found in industrial, commercial, and mechanical plant environments. The 90-degree elbow configuration is typical for routing tubing around obstructions or making clean directional changes at panel or manifold connections. HVAC controls, refrigeration skids, chemical feed systems, and compressed air instrumentation lines are common installation environments. The 1/4-inch tube by MNPT end style suits a wide range of standard instrument valves, gauges, and manifold ports.

Key Features

• Double ferrule design provides a secure mechanical grip and leak-resistant seal on 1/4-inch tubing
• 90-degree elbow geometry for clean directional changes in tight tubing runs
• Brass construction meets ASTM B16 Alloy 360 and ASTM B124 Alloy 377 material standards
• Fully interchangeable with Swagelok and Parker A-Lok double ferrule fittings and components
• Domestically manufactured under ISO 9001:2008 quality standards
• ABS approved and registered under Canadian Registration requirements

Compatibility

CBC-Lok tube fittings are fully interchangeable with Swagelok and Parker A-Lok double ferrule fittings. Intermixing CBC-Lok bodies and component parts with those of other manufacturers will not adversely affect sealing ability, though use of all CBC-Lok components is recommended.

Installation Notes

Double ferrule tube fittings are typically installed by instrumentation technicians or pipefitters working on process and mechanical systems. Before installation, ensure the tubing is cut square, fully deburred, and bottomed out in the fitting body. Thread the fitting into the mating NPT port using an appropriate thread sealant or tape rated for the service fluid, and tighten the compression nut to the manufacturer's recommended turns-past-finger-tight procedure. Power down or depressurize any system before disconnecting or replacing tube fittings.
