Can the Angular swivel connector with tapered male thread, type R 31C maintain airtight and mechanical seals during repeated connections at working pressures up to 16 bar?

Yes. The Angular swivel connector with tapered male thread, type R 31C is specified for use in pneumatic systems with a working pressure up to 16 bar and is described as âeasy and quick to use for multiple assemblies without loss of sealing on the mechanical and pneumatic sides.â Constructed from nickelâplated brass with NBR seals and rated for vacuum and air over a temperature range of â20 Â°C to +80 Â°C, it is designed to maintain both airtight and mechanical seals during repeated connections at working pressures up to 16 bar, provided it is used within these specified conditions (correct mating threads, compatible media, temperature range, and routine inspection/maintenance).

Is the Angular swivel connector with tapered male thread, type R 31C suitable for vacuum and air applications across -20Â°C to +80Â°C?

Yes. The Angular swivel connector with tapered male thread, type R 31C is suitable for vacuum and air applications within the -20Â°C to +80Â°C range. It is designed for pneumatic systems, supports vacuum and air as working media, has a working pressure of 16 bar, nickel-plated brass construction, and NBR sealing compatible with that temperature range.

How do I properly maintain the Angular swivel connector with tapered male thread, type R 31C to ensure long-term sealing performance?

To properly maintain the Angular swivel connector with tapered male thread, type R 31C and ensure long-term sealing performance, follow these steps: 1. Regular inspection - Check the connector visually before each use for signs of wear, corrosion, cracks or damage to the nickel-plated brass body and the tapered male thread. - Inspect the NBR sealing surfaces and any O-rings for cuts, hardening, deformation or swelling. 2. Cleaning - Clean threads and sealing surfaces with a soft brush and a mild solvent compatible with NBR (e.g., isopropyl alcohol). Avoid aggressive solvents that swell or degrade NBR. - Remove debris, dust and residue from the swivel mechanism to prevent mechanical abrasion. 3. Lubrication - Apply a thin, compatible lubricant to the tapered thread and swivel bearing to reduce wear and ensure smooth assembly. Use lubricants approved for NBR (silicone-based or mineral oil compatible greases). Avoid petroleum-based oils that attack NBR. - Re-lubricate periodically depending on service frequency and environmental conditions. 4. Correct assembly and torque - Assemble carefully to avoid cross-threading. Engage threads by hand first, then tighten to the manufacturerâs recommended torque if specified; if not specified, tighten to a firm hand-plus small wrench turnâdo not over-torque to prevent thread and seal damage. - Ensure alignment of connected components to avoid side loads that stress seals. 5. Pressure and temperature limits - Operate within specified limits: up to 16 bar, medium vacuum or air, and temperatures between -20Â°C and +80Â°C. Exceeding these limits shortens seal life and may cause failure. 6. Replacement schedule - Replace NBR seals and any worn O-rings at first sign of degradation or on a preventive schedule based on duty cycle (e.g., annually in normal use; more frequently in harsh environments). - Replace the Angular swivel connector with tapered male thread, type R 31C if the nickel plating is severely worn, threads are damaged, or swivel action becomes rough. 7. Storage - Store in a clean, dry environment away from direct sunlight, ozone sources and extreme temperatures to prevent NBR aging and brass corrosion. 8. Environmental considerations - Avoid exposure to aggressive chemicals, oils incompatible with NBR, or prolonged UV/ozone exposure. If such exposure is unavoidable, increase inspection and replacement frequency. Following these practices will help maintain the sealing integrity and mechanical reliability of the Angular swivel connector with tapered male thread, type R 31C over its service life.
