PFPE Grease Solution for Valves Handling Hydrogen Fluoride Gas

In fluorochemical and specialty gas industries, media containing hydrogen fluoride (HF) place extremely high demands on sealing and lubrication materials. Recently, a customer entered our store through a silicone sealing grease product link and directly asked whether we could supply YBS-1768, a PFPE-based sealing grease, for a valve application.

The customer explained that the valve medium was HF-containing gas, operating at 50–65°C, with EPDM gaskets. Such conditions require outstanding chemical inertness, corrosion resistance, and elastomer compatibility.

As a professional manufacturer of perfluoropolyether (PFPE) lubricants, Jialede promptly evaluated the operating conditions. We informed the customer that YBS-1768, a PFPE-based sealing grease, offers excellent resistance to aggressive chemical gases. At the same time, we highlighted YBS-1672, which has proven long-term performance in hydrogen fluoride environments, maintaining stability without degradation.

After further technical discussion regarding valve design, sealing structure, and maintenance intervals, we recommended a high-purity PFPE grease solution to ensure maximum service life and system safety. Ultimately, the customer fully recognized Jialede’s expertise in HF-resistant lubrication solutions and placed an order for 10 kg of PFPE grease for critical valve equipment.

Jialede remains committed to application-driven development, delivering safe, reliable PFPE lubrication and sealing solutions for HF, highly corrosive gases, and other demanding operating conditions.
