Keeping an HPLC system running is often a parts problem, not a technology problem. The pump diaphragms wear out, and suddenly you encounter pressure drift, leakage, or unstable baselines. This technical note introduces our two compatible PTFE diaphragm sets that replace common Shimadzu® OEM part numbers:228-55272-41 – For LC-30AD / i-Series 228-32784-91 – For LC-10/20/2010 / LC-30ADSF family (replaces old numbers 228-24311-01, 228-31828-00, Sciex™ 4425151)Quick OverviewOur Product...

Note: OEM part numbers are for identification only. XHH Seals is an independent manufacturer and is not affiliated with ERSA®. If you are maintaining ERSA selective soldering or wave soldering equipment, some seals and small consumable parts are hard to source or have long lead times. XHH Seals can manufacture compatible replacement parts based on your drawing or physical sample. We do not claim these are stocked items. This page is to show what we can produce as custom replacements. Part...

Gate valves used in oil, gas, and high-pressure hydraulic systems demand absolute sealing integrity under severe static sealing conditions. Traditional elastomer seals often degrade under high pressure, chemical exposure, or thermal cycling. To overcome these challenges, PTFE Spring Energized Seals have become the preferred self-energizing solution for long-term gate valve sealing applications where safety, reliability, and performance are critical. Why Gate Valves Need High-Performance...
