Is the CEJN 116 quick connect plug with GW with valve, hardened steel compatible with standard hydraulic hoses and fittings at 1500 bar working pressure?

Yes . the CEJN 116 quick connect plug with GW with valve, hardened steel is designed for hydraulic systems at very high pressures and is compatible with standard high-pressure hydraulic hoses and fittings rated for 1500 bar, provided that the mating coupling, hose assembly and other components are likewise rated and dimensionally compatible. Key facts from the product description supporting compatibility: - Working pressure (connected coupling): 1500 bar - Burst pressure: 3000 bar - Material: hardened, galvanized steel (suitable for high-pressure use) - Sealing: NBR (standard hydraulic seal material) - Nominal diameter: 2.5 mm; flow: 6 l/min (Îp = 4 bar) Ensure the mating coupling has the correct internal thread (GW) and pressure rating, the hose ends and fittings are rated to 1500 bar, and NBR seals are acceptable for your fluid and temperature range (â30Â°C to +100Â°C). Follow manufacturer assembly and safety guidelines.

Can CEJN 116 quick connect plug with GW with valve, hardened steel be used interchangeably with other 1500 bar hydraulic quick couplings?

No - CEJN 116 quick connect plug with GW with valve, hardened steel cannot be assumed interchangeable with other 1500 bar hydraulic quick couplings without verification. Although it is rated for 1500 bar (connected) and made of hardened galvanized steel with NBR seals, interchangeability depends on matching coupling series/design, thread type (GW/internal thread), valve compatibility, nominal diameter (2.5 mm), flow characteristics (6 l/min at Îp=4 bar), sealing geometry and pressure/burst specs. Mating with a different manufacturerâs coupling that has incompatible valve poppet, seal profile, or dimensions can cause leaks, pressure loss or failure. Always confirm mechanical and sealing compatibility (thread, valve type, coupling series) and perform pressure testing or consult CEJN documentation before interchange.

Can CEJN 116 quick connect plug with GW with valve, hardened steel withstand repeated cycles at 1500 bar without seal degradation?

No reliable guarantee. likely not without seal degradation over many cycles. Why: The CEJN 116 quick connect plug with GW with valve, hardened steel is rated for extremely high static and dynamic pressures (working pressure 1500 bar connected; burst 3000 bar) and is made of hardened galvanized steel. However, the sealing material is NBR (nitrile rubber), which has practical limits under high-pressure cyclic loading, temperature, and contamination. Repeated high-pressure cycles at 1500 bar will subject the NBR seal to extreme mechanical stress, potential extrusion, microâfatigue, hardening or cracking, and accelerated wearâespecially if cycles are frequent, involve pressure spikes, elevated temperature, or particulates. Factors that determine seal life: - Cycle frequency and duty (number of cycles per hour/day) - Peak pressure profile (steady 1500 bar vs brief spikes above rating) - Temperature (NBR rated -30Â°C to +100Â°C; endurance worsens near extremes) - Hydraulic fluid compatibility and contamination - Presence/quality of backup rings or extrusion protection in the coupling - Assembly, alignment and torque during use Recommendations: - Do not assume unlimited cyclic life; perform validation testing under your specific duty cycle. - If you require high-cycle performance at 1500 bar, consult CEJN for data on cycle life or consider alternative seals (e.g., HNBR, FKM) or couplings with extrusion protection/backup rings designed for high-cycle service. - Implement contamination control, proper maintenance, and periodic seal inspection/replacement. Conclusion: The CEJN 116 quick connect plug with GW with valve, hardened steel is designed for 1500 bar operation, but NBR seals are likely to degrade with repeated cycles at that pressureâverify with manufacturer tests or select more robust sealing solutions for high-cycle applications.
