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

Parker Veriflow UltraSeal 接頭旨在用于高純度正壓和真空應(yīng)用，包括氣體分配管線，管道系統(tǒng)和氣體箱。它們非常緊湊，可以在緊密的管焊接系統(tǒng)中快速組裝。UltraSeal 配件的O形圈密封設(shè)計(jì)具有出色的抗振動和熱循環(huán)性能，并消除了陷入?yún)^(qū)域的紊流。當(dāng)壓蓋的端面與閥體的表面完全形成金屬對金屬的接觸時，安裝接頭會形成氦氣密封，從而壓縮閥體凹槽中的O形圈。壓蓋端面和閥體的O形圈槽經(jīng)過精密加工，可以接受金屬（不銹鋼）或合成O形圈密封。閥體和壓蓋的孔徑在所有尺寸上均匹配，從而消除了墊圈的侵入并提供了更平滑的流動路徑。UltraSeal配件組件可用標(biāo)準(zhǔn)316L，316L VAR和316L VIM / VAR不銹鋼制成，并可提供極低的Ra內(nèi)部表面光潔度或電拋光，以滿足高純度管路系統(tǒng)的要求。所有配件均在100級無塵室中組裝，并根據(jù)聯(lián)邦標(biāo)準(zhǔn)209E進(jìn)行了驗(yàn)證。它們使用質(zhì)譜儀進(jìn)行了氦氣泄漏測試，以確保在要求過程清潔度至關(guān)重要的苛刻工業(yè)應(yīng)用中的性能和可靠性。額定溫度取決于O形圈密封材料的選擇。

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.
