SWAGELOK MALE WBV-SS SWAGELOK 1/2" X 1/2" MALE VCR 316SS BULKHEAD FIT PARKER 8-8 WBV-SS SS-8-VCR-61SP

Swagelok SS-8-VCR-61SP is a male VCR bulkhead fitting constructed from 316 stainless steel. Designed for high-purity and high-integrity fluid systems, this fitting provides a reliable metal-to-metal seal for applications requiring leak-tight performance. It directly cross-references the Parker 8-8 WBV-SS and is ideal for use in semiconductor, chemical, and pharmaceutical industries.

Overview

This bulkhead fitting solves the challenge of creating a leak-free connection through a panel or enclosure. It is designed for engineers and technicians who need to route high-purity gas or liquid lines while maintaining system integrity. The male VCR (Vacuum Coupling Radiation) design ensures a positive seal under vacuum or pressure, and the 316 stainless steel construction offers excellent corrosion resistance. Typical scenarios include gas distribution systems, analytical instrumentation, and ultra-high-purity (UHP) lines.

Key Features

• 316 Stainless Steel Construction: Provides superior corrosion resistance and durability for demanding environments, including corrosive media and high-temperature applications.
• Male VCR Connections: Features standard 1/2" male VCR ends for easy integration with existing VCR glands and female fittings, ensuring a consistent, leak-tight seal.
• Bulkhead Design: Allows the fitting to be mounted through a panel or wall, providing a stable feed-through point for tubing lines and enabling compact system layouts.
• Cross-Reference Compatibility: Directly replaces Parker 8-8 WBV-SS male VCR bulkhead fitting, offering a drop-in solution for maintenance or system upgrades.
• High Purity Performance: Manufactured to Swagelok's stringent quality standards, ensuring low particulate generation and compliance with clean process requirements.

Applications

• Semiconductor gas delivery systems where clean, leak-free connections through tool enclosures are critical.
• Chemical processing plants requiring corrosion-resistant fittings for aggressive fluids or high-temperature lines.
• Pharmaceutical and biopharmaceutical manufacturing for sterile fluid transfer and clean-in-place (CIP) systems.
• Analytical instrumentation (GC, mass spectrometry) where sample integrity depends on inert, low-dead-volume connections.
• High-vacuum research apparatus needing reliable feed-through fittings that maintain vacuum integrity.

Compatibility & Cross-References

This Swagelok SS-8-VCR-61SP bulkhead fitting is designed to directly replace the Parker 8-8 WBV-SS. Both fittings share the same dimensions, thread type, and sealing mechanism. It is compatible with standard 1/2" VCR glands, gaskets, and female VCR fittings from Swagelok, Parker, and other major manufacturers. Always verify system requirements before installation.

FAQ

• What is the difference between this fitting and a standard VCR connector? This is a bulkhead version, meaning it has a threaded body that allows mounting through a panel and securing with a nut, providing a fixed feed-through point. A standard VCR connector does not include panel-mount capability.
• Can I use this fitting with Parker VCR glands? Yes, the male VCR interface is standardized. It mates with Parker VCR glands and female fittings without issues.
• Is this fitting suitable for high-vacuum service? Yes, the 316 stainless steel construction and VCR metal seal design make it appropriate for high-vacuum applications down to 10^-8 Torr, provided proper gaskets and torque are used.
• What is the maximum operating pressure and temperature? While exact ratings depend on installation and mating components, Swagelok VCR fittings typically handle pressures up to 6000 psig (414 bar) and temperatures from -325°F to 1200°F (-198°C to 648°C) depending on gasket material. Consult Swagelok technical data for specific limits.
