In demanding industries such as oil & gas, chemical processing, LNG cryogenic, and high-pressure / high-temperature (HPHT) service, the valve stem sealing system is one of the most critical challenges for engineers. Under the combined assault of pressure cycling, extreme temperatures, and aggressive media, traditional elastomeric seals (such as O-rings) fail prematurely — resulting in leakage, fugitive emissions, and unplanned downtime. XHH Seals specializes in developing Spring...

1. The Problem: Leakage in CryoMac® 3 LNG Nozzles CryoMac® 3 and 3-50M nozzles are widely used in LNG fueling stations and vehicle refueling systems. Despite their robust design, leakage during or after fueling remains a frequent maintenance issue. Leakage typically occurs in two modes:Coupled leakage — LNG or vapor escapes during fueling; Uncoupled leakage — vapor continues to vent after the nozzle is disconnected.Both are caused by degradation of the nozzle’s primary sealing components,...

According to the original catalog description, AR10414-113-WC is a spring-energized rotary lip seal made from a PTFE + PHB compound, specified for a temperature range of -40°C to +260°C and supplied in brown color. This seal is used in high-performance rotary...

In hot melt adhesive systems, the piston pump is the core of the melter. Once the pump seal wears out, output becomes unstable, leakage increases and unplanned downtime becomes more frequent. The OEM Nordson® pump service kit 105450 is widely referenced as a “Pump A seal kit / pump seal kit” for hot melt piston pumps. XHH Seals manufactures a compatible replacement kit, cross-referenced to 105450, to help maintenance teams rebuild their pumps in a cost-effective way. Note: 105450 is an OEM...

All seals supplied by XHH are our own engineered products. The AMAT 3700-01485 seal appears in spare-parts lists for P5000, Centura and Endura platforms as a large dynamic radial seal used on robot or actuator shafts. Maintenance teams usually search this part number when planning robot refurbishment or troubleshooting vacuum integrity...

Hot melt gun performance often fails at one small point: the internal spring-loaded seal. For systems using the Nordson® 1071968 “seal, spring”, leakage, stringing, or short service life usually mean this seal is worn or no longer properly energized. XHH Seals manufactures spring-energized seals for these applications, giving you a stable, cost-effective alternative supply. Nordson® and all OEM part numbers are used for identification only. XHH is an independent manufacturer. What Customers...

Cryogenic seals work in a very harsh corner of engineering. Temperature is far below zero. Media can be LNG, liquid nitrogen, oxygen, or hydrogen. If the seal fails, the system may leak, freeze, or even form dangerous ice plugs. As a specialized cryogenic seal manufacturer, we design seals that stay tight from cool-down to warm-up. This article gives an engineer-level view of how these seals work and how to specify them for real projects. 1.What Makes Cryogenic Seals Different? Most standard...

Based on publicly available spare parts documentation, AMAT 3700-01484 is listed as a dynamic radial seal often found in vacuum tools involving robot or actuator assemblies (e.g., P5000, Centura, Endura platforms). Typical Dimensional Specifications:Description: SEAL DYN RADIAL / DYN EXT RADIAL Outer Diameter (OD): 1.241 in Inner...

Nordson® is a registered trademark of Nordson Corporation. XHH Seals is an independent manufacturer of compatible replacement parts. 1. Role of the Piston Cup Seal in a Dispensing Pump In many adhesive lines, a small piston cup seal decides if production is stable or not. The seal is mounted on the piston inside the pump or cylinder. It generates the dynamic seal between the piston outer diameter and the cylinder bore. In Nordson®-type dispensing pumps and jet valves, compressed air moves the...

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...
