VCR-style grooved gasket face seal fittings have numerous applications. Widely utilized in the semiconductor industry, these metal face seal fittings are ideal for processes where precision and contamination control are essential.
What Are Grooved Gasket Face Seal Fittings?
Grooved gasket face seal fittings provide elevated leak resistance and prevent the over-tightening of parts.
Applications
Semiconductor Manufacturing
Grooved gaskets are capable of handling ultra-high purity (UHP) gases, including but not limited to:
- Nitrogen
- Oxygen
- Argon
- Helium
- Hydrogen
These UHP gases are commonly used in semiconductor manufacturing processes such as etching and chemical vapor deposition. Our grooved gasket face seal fittings help prevent UHP gas leakage, maintaining the purity of the gas as it flows through the system. Additionally, we include a stop feature, virtually eliminating over-tightening and protecting the gas delivery system from potential damage.
Hy-Tech Fittings – Grooved Gasket Variations
Standard Design Grooved Gasket Face Seal Fitting
Hy-Tech Fittings Part Number: 4-SS
Specifications:
- Inner Diameter (ID): 0.280”
- Outer Diameter (OD): 0.490”
- Thickness: 0.062”
Our Standard Design Grooved Gasket is suitable for a wide range of applications requiring general sealing.
Minimum Dead Volume Grooved Gasket
Hy-Tech Fittings Part Number: 4-001
Specifications:
- ID: 0.298”
- OD: 0.490”
- Thickness: 0.062”
Our Minimum Dead Volume Grooved Gasket is purposely designed for systems requiring a bore line seal, which minimizes dead volume (unfilled space within the fitting). This VCR-style face seal fitting is ideal for a wide range of UHP gas applications where even trace contaminants could compromise the system.
No-Overtighten Grooved Gasket
Hy-Tech Fittings Part Number: 4-NO
Specifications:
- ID: 0.280”
- OD: 0.490”
- Thickness: 0.080”
The No-Overtighten Grooved Gasket prevents damage caused by over-tightening without compromising the seal. Its thicker design helps prevent the gasket from being compressed beyond optimal limits, which is crucial in high-pressure or sensitive sealing environments.
Dual-Mate Grooved Gasket
Hy-Tech Fittings Part Number: 4-DMR
Specifications:
- ID: 0.210”
- OD: 0.490”
- Thickness: 0.080”
Our Dual-Mate Grooved Gasket is comparable to our No-Overtighten design and contains two separate sealing points.
Many of our grooved gaskets are available with or without a retainer. Hy-Tech Fittings’ retainers are comprised of ethylene tetrafluoroethylene (ETFE), a lightweight and durable material that allows the gasket to hold securely within the fitting assembly. All of our grooved gasket face seal fittings are interchangeable with VCR-style fittings.
The Hy-Tech Difference
Providing 900% more seal support than standard flat gaskets, Hy-Tech grooved gaskets offer unbeatable leak resistance in static and turbulent environments. Contact us today to learn more about our VCR-style grooved gasket face seal fittings or any of our other products.
