1. Overview: The Two Critical Sealing Points of the JC Carter 50E701 Nozzle The JC Carter 50E701 series nozzle (including models 50E701-1, -2, and -3) is a standard-issue component in LNG (Liquefied Natural Gas) fueling infrastructure worldwide. Its operational reliability and safety depend entirely on two critical cryogenic sealing components. According to the official service manual's troubleshooting guide, nozzle leakage can be traced to two primary failure points :An external seal that...

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,...

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...

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...
