Parker 50-63-NI Specialty Gas Cylinder Gasket — Pack of 25

PARKER · Specialty Gas Seal · NI-Plated Brass/Steel · 50-63 Size · In Stock

The Parker 50-63-NI is a precision-machined specialty gas cylinder gasket sized for 50-63 mm port interfaces, manufactured with nickel-plated (NI) brass and stainless steel to resist corrosion in aggressive specialty-gas service. Supplied as a 25-piece multi-pack, this consumable seal is regularly restocked by gas-panel builders, laboratory gas-distribution contractors, and field-service engineers who maintain Allen-Bradley process-control racks, Siemens SIMATIC gas-panel I/O subsystems, and electronic-grade gas cabinets running in semiconductor fabs and analytical-instrument rooms.

The “NI” plating is selected specifically for dry, high-purity specialty gases (calibration mixes, zero-air, hydrogen, helium, argon, semiconductor process gases) where standard elastomer O-rings or uncoated copper gaskets would outgas, oxidize, or shed particulates. For facilities that prefer to standardize on Parker consumables alongside their PLC, HMI, and process-transmitter hardware, KOEED keeps the 50-63-NI in active inventory and can bundle the gasket with a full instrument-list BOM in a single shipment.

Key Specifications

Datasheet Highlights

• NI-plated sealing surface — nickel plating prevents oxidation of the gasket face during long shelf life, even when the cylinder remains idle for months between calibrations. This reduces leak paths at the regulator-to-cylinder interface.
• Dual-material construction — the brass/steel core gives the gasket mechanical strength at regulator torque, while the nickel skin delivers the chemical compatibility demanded by reactive or ultra-dry specialty gas mixes.
• 50-63 size coverage — the 50-63 designation is a Parker size class that maps to common specialty-gas cylinder valve outlets and panel-header ports. Specifying “50-63-NI” is sufficient to cross the entire 50-63 family of regulators and header fittings.
• Clean-room friendly finish — the NI plating is well below the particulate-shed threshold of uncoated copper crush gaskets, making it suitable for tool hook-up in fab-side gas cabinets and for analyzer-grade sample lines.
• Multi-pack format (25 pcs) — one carton covers a quarterly service cycle for a mid-sized gas panel, removing the need for frequent re-orders and avoiding line-down events when one cylinder swap is overdue.

Typical Applications

• Specialty & calibration gas cylinders — regulator-side seal on zero-air, span gas, and NIST-traceable calibration cylinders used in CEMS, process-analyzer shelters, and emissions-monitoring skids.
• Semiconductor fab gas cabinets — bulk-gas and specialty-gas cylinder connections feeding process tools, where the NI plating survives vapor-phase corrosion and resists particle generation in the MFC manifold.
• Laboratory gas distribution — lab bench turret headers, gas chromatography (GC) supply lines, and ICP-MS feed manifolds in research and analytical labs.
• Process gas analyzers — sample-handling conditioning panels and probe-side connections for paramagnetic, NDIR, FTIR, and laser-tunable analyzers on Allen-Bradley or Siemens control racks.
• Pharma & biotech process gas — pure steam, clean dry air (CDA), and nitrogen manifolds in aseptic fill-finish and bioreactor suites, where the gasket must not shed into the gas stream.
• Field service & preventive maintenance — stocked by plant I&E teams who prefer to keep a fresh 25-pack on the shelf for regulator rebuilds during scheduled cylinder change-outs.

Related Modules & Cross-Reference

The Parker 50-63-NI is a consumable seal, not a control module, so it is typically ordered alongside the automation hardware it sits in front of. The following KOEED part lines are common co-requisites for gas-panel builders and analyzer integrators.

If you are validating a full gas-panel BOM — regulator, NI gasket, MFC, pressure transmitter, and PLC analog I/O — send the entire list to our quotation desk and we will respond with one consolidated availability & price line per part. The AI Diagnostic Tool can also help identify a cross reference for legacy or discontinued Parker size classes that are no longer in the official catalog.

Warranty & Authenticity

• Sourced as genuine Parker — every 50-63-NI gasket ships in original Parker packaging with lot traceability, so your QC team can verify material and plating on receipt.
• Pre-shipment visual inspection — plating finish, flatness, and edge condition are checked before the carton leaves our warehouse; gaskets with visible plating voids or nicks are removed from the pack.
• Worldwide shipping — DHL / FedEx / UPS standard transit, with export documentation prepared for North America, EU, Middle East, Southeast Asia, and Latin America.
• 24-hour quote response — send the part number and quantity to Moritta@KOEED.COM on a business day and you will receive availability and price the same day.
• BOM-level consolidation — the 50-63-NI is regularly bundled with PLC, HMI, transmitter, and regulator lines on a single purchase order, so your receiving team only chases one shipment.
