Does Connector - pipe quadrant, brass, type AI 13510 support use with plastic hoses like polyamide without additional sealing?

Connector - pipe quadrant, brass, type AI 13510 supports use with plastic hoses like polyamide without additional sealing. The product description explicitly states it is designed for plastic pipes and hoses (e.g., polyamide). Tightness is achieved by the compression of a ring onto the connected pipe and by the nut pressing the pipe with the ring into the socket, so no separate external sealant or additional sealing components are required for proper sealing when used within the specified pipe diameter range (4â14 mm). Ensure the polyamide hose outer diameter matches the connector size and follow installation torque/specification guidelines per EN 1254-2 and manufacturer instructions to avoid leaks.

Can Connector - pipe quadrant, brass, type AI 13510 be used with plastic pipes or hoses (e.g., polyamide) without special adapters?

Yes. Connector - pipe quadrant, brass, type AI 13510 is designed for use with plastic pipes and hoses (e.g., polyamide) as well as copper, brass, steel and aluminium, for external diameters 4â14 mm. Tightness is achieved by the compression ring and nut, so no special adapters are required for compatible plastic pipes-just ensure the pipe OD falls within the specified range and follow proper installation (cut square, deburr, insert fully, tighten to recommended torque). Standard: EN 1254-2.

Is Connector - pipe quadrant, brass, type AI 13510 suitable for repeated disassembly/reassembly with plastic hoses (polyamide)?

Connector - pipe quadrant, brass, type AI 13510 is described as suitable for connecting copper, brass, steel, aluminum and plastic pipes and hoses (e.g., polyamide) with external diameters 4â14 mm. The connection sealing relies on a compressive ring (olive) and a nut that presses the ring and pipe into the socket (compression fitting). Material: brass. Standard: EN 1254-2. Given that description, Connector - pipe quadrant, brass, type AI 13510 is suitable for repeated disassembly and reassembly with polyamide (PA) hoses only with reservations: - Compression fittings are generally reusable a limited number of times, but the olive (compression ring) deforms during initial installation to form a metal-to-metal seal. Reusing the same olive often compromises sealing and can cause leaks; best practice is to replace the olive and, in many cases, the nut when reinstalling. - Polyamide hoses are compatible with brass fittings, but repeated full disassembly/reassembly stresses the hose end and can cause ovalization, surface damage or reduced sealing over time. Use of a new olive and careful, limited re-tightening reduces risk. - For reliable repeated service, consider using replacement olives and nuts each time or use fittings specifically specified by the manufacturer as reusable. Also inspect hose ends for damage and ensure proper tightening torque per manufacturer guidance. Conclusion: Connector - pipe quadrant, brass, type AI 13510 can be used with polyamide hoses and withstand occasional disassembly/reassembly, but for repeated cycles replace the compression ring (and ideally the nut) and inspect/replace hose ends to ensure leak-free connections. Continuous frequent disassembly/reassembly is not recommended without using parts intended for reuse.
