Is the GUILLEMIN connector with BSP female thread, stainless steel suitable for steam or gas transfer?

No. The GUILLEMIN connector with BSP female thread, stainless steel is explicitly stated as not suitable for the transmission of steam and gases. It is intended for industrial and handling installations of bulk substances and granulates. Although made of AISI 316 stainless steel, rated to 16 bar, and fitted with black FKMâVITON sealing (operating â10Â°C to +180Â°C), the product description prohibits use with steam and gases.do not use it for those media.

Can the GUILLEMIN connector with BSP female thread, stainless steel be used with food-grade products or in pharmaceutical environments?

The GUILLEMIN connector with BSP female thread, stainless steel is made of AISI 316 and meets EN 14420-8/NF-E-29572, which are positive indicators for industrial durability. However its sealing is black FKM (Viton) and the product is specified for bulk substances and granulates, not for steam or gases. FKM can be food-contact compliant in some formulations but is not universally certified for all food or pharmaceutical applications; likewise the connector description does not state any food-grade or pharmaceutical certifications (e.g., FDA, EU 10/2011, USP Class VI, or EC 1935/2004). Therefore, without explicit material and certification evidence for food/pharma use and compatibility testing for your specific products and sanitization procedures, the GUILLEMIN connector with BSP female thread, stainless steel should not be assumed suitable for food-grade or pharmaceutical environments. Obtain supplier certification or choose components explicitly certified for food/pharma use.

What maintenance is required for the GUILLEMIN connector with BSP female thread, stainless steel?

Maintenance for the GUILLEMIN connector with BSP female thread, stainless steel - Regular inspection: Check the GUILLEMIN connector with BSP female thread, stainless steel visually before each use and periodically during operation for signs of wear, corrosion, cracks or deformation, especially on the sealing face and thread. Inspect the AISI 316 body for pitting or surface damage. - Seal check and replacement: Inspect the black FKMâVITON rubber seal for cuts, hardening, swelling or chemical degradation. Replace the seal if any damage or loss of elasticity is found. Keep spare seals compatible with FKMâVITON and the operating temperature range (â10Â°C to +180Â°C). - Cleaning: Clean the connector and sealing surfaces after use with compatible cleaning agents that do not attack stainless steel or FKM (avoid strong alkalis and chlorinated solvents). For bulk solids and granulates, remove residues mechanically or with compressed air; avoid abrasive tools that can damage sealing faces. - Thread care: Keep the BSP female thread clean and free of debris. Lightly lubricate threads with a lubricant compatible with FKM and AISI 316 if assembly torque is high or to prevent galling, but avoid excess lubricant that could attract dust from granulates. - Corrosion prevention: Although AISI 316 is corrosionâresistant, in aggressive environments rinse and dry the connector after exposure to chlorides or contaminants. Store in a dry, ventilated place. - Pressure and temperature checks: Ensure operation stays within the specified working pressure (16 bar) and temperature range (â10Â°C to +180Â°C). After any overpressure or overheating event, inspect the connector and seal thoroughly and replace if compromised. - Functional test: Periodically assemble and test the coupling under operating conditions to confirm leakâfree performance. If leaks occur, check the seal seating, sealing face condition and thread engagement. - Replacement intervals: Replace seals according to service conditions and frequency of use; replace the connector if structural damage, severe corrosion, or persistent leaks cannot be corrected. Following these steps will help maintain safe, reliable service for the GUILLEMIN connector with BSP female thread, stainless steel in industrial handling of bulk substances and granulates.
