Parker Veriflow UltraSeal fittings O型圈端面密封接头
Parker Fittings接头 Face Seal Fittings
UltraSeal O-ring Face Seal Fitting (sizes up to 3/4 inch)

Parker Veriflow UltraSeal 接头旨在用于高纯度正压和真空应用，包括气体分配管线，管道系统和气体箱。它们非常紧凑，可以在紧密的管焊接系统中快速组装。UltraSeal 配件的O形圈密封设计具有出色的抗振动和热循环性能，并消除了陷入区域的紊流。当压盖的端面与阀体的表面完全形成金属对金属的接触时，安装接头会形成氦气密封，从而压缩阀体凹槽中的O形圈。压盖端面和阀体的O形圈槽经过精密加工，可以接受金属（不锈钢）或合成O形圈密封。阀体和压盖的孔径在所有尺寸上均匹配，从而消除了垫圈的侵入并提供了更平滑的流动路径。UltraSeal配件组件可用标准316L，316L VAR和316L VIM / VAR不锈钢制成，并可提供极低的Ra内部表面光洁度或电抛光，以满足高纯度管路系统的要求。所有配件均在100级无尘室中组装，并根据联邦标准209E进行了验证。它们使用质谱仪进行了氦气泄漏测试，以确保在要求过程清洁度至关重要的苛刻工业应用中的性能和可靠性。额定温度取决于O形圈密封材料的选择。

Parker Veriflow UltraSeal fittings are intended for use in high-purity positive pressure and vacuum applications, including gas distribution lines, piping tube systems, and gas boxes. They are highly compact and allow for quick assembly in tight tube welded systems. UltraSeal fittings' o-ring seal design provides excellent resistance to vibration and thermocycling, and eliminates turbulence in entrapment zones. Fitting couplings form a helium leak-tight seal when the face of the gland makes full metal-to-metal contact with the face of the body, compressing the o-ring in the body groove. The gland face and body o-ring groove are precision machined to accept either metallic (stainless steel) or synthetic o-ring seals. The bore diameter of body and gland are matched in all sizes, thereby eliminating intrusion of the gasket and providing a smoother flow path. UltraSeal fitting components are available in standard 316L, 316L VAR, and 316L VIM/VAR stainless steels and can be supplied with extremely low Ra internal surface finishes or electropolish to meet the requirements of high purity tubing systems.

O-ring Face Seal Fitting (sizes up to 3/4 inch) – UltraSeal

All fittings are assembled in a class 100 cleanroom and validated per Federal Standard 209E.
They are helium leak tested using a mass spectrometer to ensure performance and reliability in demanding industrial applications where process cleanliness is critical. Temperature ratings are governed by the choice of o-ring seal material.
