Dichtungslösungen für die LNG-Industrie

Here's the list of Top LNG Dispenser Seal Manufacturers Worldwide in 2025, specifically for LNG fueling nozzles (used at LNG refueling stations):

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,...

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...
