SS316 Core Flange Isolating Gasket Kits
Model:KVCS 100
SS316 Core Flange Isolating Gasket kits is a high reliability gasket used for both isolating and general sealing purposes in Very Critical Services. The gasket has a proven track record of integrity in aggressive sealing situations. Flange Isolating Gasket for High Pressure is suitable in all services up to and including ANSI 2500# and API 10,000# classes. Flange Isolating Gasket for High Pressure is designed for service where the cost of gasket failure cannot be tolerated. Flange Isolating Gasket for High Pressure gasket consists of a PTFE (Teflon) spring-energized face seal, or an elastomeric o-ring, seated in an isolating laminate, which is permanently bonded to a high-strength stainless steel 316 metal gasket core.
SS316 Core Flange Isolating Gasket Kits – KVCS 100
Kaxite Sealing, a leading China flange insulation gasket manufacturer, presents the KVCS 100 SS316 Core Flange Isolating Gasket Kit – a high‑reliability sealing solution engineered for Very Critical Services (VCS) where gasket failure is not an option. This advanced isolating gasket combines a high‑strength stainless steel 316 (SS316) metal core with a permanently bonded isolating laminate and a PTFE spring‑energized face seal or elastomeric O‑ring. The result is a pressure‑activated sealing system that delivers uncompromised integrity in the most aggressive service conditions, including high‑pressure, high‑temperature, and highly corrosive environments.
Why KVCS 100? Unlike conventional gaskets that rely on high bolt loads to achieve a seal, the KVCS 100's unique pressure‑activated sealing mechanism requires far less bolt stress while providing superior sealing performance. It is rated for service up to and including ANSI 2500# and API 10,000# (15,000 psi) classes, making it the preferred choice for oil and gas, petrochemical, subsea, and critical infrastructure applications. The gasket's inner diameter is precisely matched to the flange bore, eliminating turbulent flow and protecting flange faces from erosion and corrosion. With replaceable seal elements housed in a reusable retainer, the KVCS 100 offers long‑term cost efficiency and maintenance flexibility.
As a trusted flange isolation gasket supplier in China, Kaxite offers the KVCS 100 in any flange specification (ANSI, ASME, API, MSS, BS, DIN, AS, and custom), with sizes to match all standard and non‑standard flanges. Whether you require RTJ flange isolation, raised‑face sealing, or protection against galvanic corrosion, we deliver consistent quality with full material traceability and pressure test certification.

- A: The KVCS 100 is rated for service up to ANSI 2500# and API 10,000# (15,000 psi). It is designed for the most demanding high‑pressure applications in oil and gas, subsea, and critical process industries. For higher pressure requirements, please consult our technical team.
- Q: Can the KVCS 100 be used with ring‑joint (RTJ) flanges?
- A: Yes. The KVCS 100 is designed to seal in RTJ, raised‑face, flat‑face, and slip‑on flanges. It can even mate mismatched RTJ with raised‑face flanges, eliminating the need for expensive flange modifications or replacements.
- Q: Does the KVCS 100 provide electrical isolation for cathodic protection?
- A: Absolutely. The isolating laminate and seal materials provide reliable electrical isolation, preventing stray current corrosion and supporting cathodic protection systems. It also prevents galvanic corrosion when mating dissimilar metal flanges.
- Q: Is the KVCS 100 suitable for sour gas (H₂S) service?
- A: Yes. The SS316 core and PTFE seal materials are inherently resistant to H₂S and CO₂. We offer NACE MR0175 / ISO 15156 certification on request, ensuring compliance with international sour service standards.
- Q: Can the seal elements be replaced without changing the entire gasket?
- A: Yes – this is a key advantage. The KVCS 100 features replaceable seal elements in a reusable retainer. This design significantly reduces lifecycle costs and maintenance downtime, as only the seal needs to be replaced during routine maintenance.
- Q: What flange standards can the KVCS 100 be manufactured to?
