Is the GUILLEMIN connector with hose end, stainless steel suitable for steam or gas transmission?

No. The GUILLEMIN connector with hose end, stainless steel is not suitable for steam or gas transmission. The product description explicitly states it is intended for industrial and bulk material handling (granules) and is not suitable for steam and gas.

Can the GUILLEMIN connector with hose end, stainless steel be used with abrasive granules or will it wear prematurely?

The GUILLEMIN connector with hose end, stainless steel is designed for industrial and bulk material handling including granules, so it can be used with abrasive granules; however, abrasive media will accelerate wear on the connector and hose end interface over time. Its AISI 316 construction and FKM-VITON seal offer good corrosion and chemical resistance, but they do not eliminate mechanical abrasion. For heavy or highly abrasive granules consider additional protections (abrasion-resistant hose, sacrificial liners, more frequent inspection/replacement intervals) to avoid premature wear. Not suitable for steam or gas applications.

Does the GUILLEMIN connector with hose end, stainless steel require periodic seal replacement under heavy-use?

Yes. The GUILLEMIN connector with hose end, stainless steel uses a black FKMâVITON rubber seal that is durable and rated for â10Â°C to +180Â°C and working pressures up to 16 bar, but under heavy or continuous use the seal will experience wear, chemical ageing and compression set. Periodic inspection and replacement of the seal is recommended to maintain leakâfree performance, especially when the coupling is subjected to: - high cycle frequency or continuous operation - abrasive or particulate media (granules) - aggressive chemicals or oils that may affect elastomers - frequent pressure or temperature cycling close to the material limits Recommended practice: inspect seals regularly for cuts, deformation, hardening, swelling or loss of elasticity and replace at the first signs of deterioration or on a preventive schedule based on operating hours/cycles. Keep replacement seals in FKMâVITON matching the original specification to preserve compatibility with the connectorâs pressure and temperature ratings.
