Axial seal type
Axial static seals, commonly known as Face Seals, are designed to provide a robust barrier between two flat mating surfaces, such as flanges, valve manifolds, and cylinder end-faces. Unlike radial seals, the sealing force is applied axially through bolt tension or mechanical clamping. At Carlock Sealing, we engineer these profiles to ensure optimal contact stress across the entire surface, effectively compensating for minor hardware irregularities and ensuring a zero-leakage joint even under intense axial pressure pulses.
Q: When should I choose an axial face seal over a radial seal?
A: Axial face seals are used when the sealing surfaces are perpendicular to the axis of the hardware, such as in bolted flange connections. Carlock Sealing recommends axial designs for easy assembly in valve blocks (manifolds) where radial installation is not feasible due to space constraints.
Q: Can your face seals handle vacuum conditions?
A: Yes. By optimizing the axial squeeze (compression) and selecting high-purity materials like NBR or FKM, Carlock Sealing’s face seals can provide a gas-tight interface for vacuum chambers and low-pressure gas handling systems.
Technical Disclaimer: Axial face seals require clean, flat, and parallel mating surfaces. Any misalignment or excessive surface roughness (Ra) can compromise the seal integrity. Carlock Sealing provides material certificates (TÜV/SGS) and technical guidance on the required bolt torque and axial compression to ensure a reliable, long-term static seal.
