Industries Served

At XHH Seals, we provide advanced sealing solutions engineered for the extreme demands of the LNG (Liquefied Natural Gas) industry. Our seals deliver reliable, leak-free performance in cryogenic environments, even under severe temperature swings and high-pressure conditions.

Whether used in LNG fueling nozzles, storage tanks, transfer pipelines, pumps, or valves, our products are built to withstand intense thermal cycling, chemical exposure, and mechanical stress. We offer a comprehensive range of materials — including PTFE, PCTFE, PEEK, and cryogenic-grade elastomers — to meet the strict standards of LNG applications.

With a strong focus on safety, durability, and precision, XHH Seals empowers our partners to achieve greater efficiency, reliability, and operational excellence across the entire LNG supply chain.

Our Coal Mine Hydraulic Support Sealing System is specifically designed for the demanding underground mining environment. These high-performance seals ensure reliable operation of hydraulic jacks, cylinders, and support systems under high pressure, heavy load, and exposure to water-based emulsions. We offer a full range of piston seals, rod seals, wear rings, and dust wipers—engineered to extend service life and reduce maintenance downtime.
