Exceptional Leak Tightness for Critical ApplicationsThese fittings are designed for ultra-high purity and vacuum environments, ensuring minimal leakage and contamination. Their robust construction and metal gasket technology achieve leak rates as low as 1 x 10^-9 std cc/sec He, making them a top choice for semiconductor and UHP fluid systems.
Broad Compatibility and VersatilityAvailable in sizes ranging from 1/8 to 1-1/2 inches (with custom options), VCR face seal fittings are manufactured with compliance to ASME, ASTM, and SEMI standards. Their stainless steel construction guarantees high tensile strength, outstanding corrosion resistance, and suitability for both standard and aggressive media.
FAQ's of VCR Metal Gasket Face Seal Fittings:
Q: How do VCR Metal Gasket Face Seal Fittings ensure a reliable leak-tight connection?
A: VCR Metal Gasket Face Seal Fittings use a metal gasket, compressed between precisely machined gland faces, to create a gas-tight seal. When tightened, the metal gasket deforms slightly, filling imperfections and providing an ultra-low leak rate (1 x 10^-9 std cc/sec He), ideal for high-purity and vacuum applications.
Q: What types of applications benefit most from these fittings?
A: These fittings are optimal for ultra-high purity (UHP) gas and fluid systems, semiconductor manufacturing environments, and vacuum applications where contamination control, corrosion resistance, and superior leak integrity are critical requirements.
Q: When should the metal gasket be replaced in these fittings?
A: The metal gasket in a VCR face seal fitting should be replaced after every disassembly. Unlike other components, the gasket is single-use to maintain the required leak tightness. Reusing the gasket compromises seal integrity and risks contamination or leakage.
Q: Where can these fittings be installed for best results?
A: Install VCR Metal Gasket Face Seal Fittings in environments that demand exceptional purity, such as cleanrooms, vacuum chambers, and gas delivery systems. Their robust stainless steel construction and sealing technology ensure consistent performance even under harsh conditions.
Q: What is the process for assembling and connecting VCR face seal fittings?
A: Assembly involves aligning the gland faces, placing the single-use metal gasket between them, and tightening the male and female nuts to the specified torque. This compresses the gasket, creating a permanent, leak-tight metal-to-metal seal. Always use a new gasket for each assembly.
Q: How does the corrosion resistance of these fittings benefit users?
A: Constructed from SS 316/316L stainless steel, these fittings offer high resistance to corrosion from aggressive chemicals and media. This ensures long-term durability and reliable performance, especially in environments where integrity and contamination control are paramount.
