It delivers temporary emergency sealing for moderate to severe valve leakage to sustain operation until valve replacement can be scheduled. ## Features RS CLARE Valve Sealant 701‑L suits valves with buried injection fittings: Formulated for Christmas tree gate valves fitted with buried check valve injection fittings. Use 701‑L if standard 701 cannot be injected to overcome restricted injection pathways. 701 series contains solid sealing particles for damaged seat repair: Particles fill gate/seat scratches and cuts to retain sealing pressure and cut downtime. Validated via full-scale valve test on seats artificially damaged to 1.5 mm depth. Sour media resistance: Withstands produced hydrocarbons, high H₂S and CO₂ for harsh sour well sites. Operating temperature: 0°F to 350°F (-17.8℃ ~ 176.7℃). Non-hardening, non-coking: Non-curing formulation keeps valve operable, prevents seizure and protects sealing surfaces under high differential pressure. Good compatibility: Fully compatible with Valve Sealant 701 and Valve Lubricant 601 for combined field use. Applicable Equipment of Valve Sealant 701-L: API 6A Christmas tree gate valves with buried check valve injection fittings, emergency sealing for moderate-severe wellhead leakage as temporary well barrier repair. ## Specifications | Property | Value | |---|---| | Model | ClareTech Valve Sealant 701-L | | Base Oil | Synthetic oil | | Service Temperature | 0°F~350°F ℃ | ## Pack sizes | Pack size | Type | MOQ | Availability | |---|---|---|---| | 18kg | drum | | On request | ## Other items from this brand - [RS‑Clare Waterguard (SW2‑LF) Extreme‑Pressure Grease, High Water‑Resistant Marine Lubricating Grease, 12.5kg/Pail](https://www.fl-sz.cn/en/products/rs-clare-waterguard-sw2-lf-extreme-pressure-grease-high-water-resistant-marine-lubricating-grease-12-5kg-pail) - [RS Clare Claretech HFL Special‑Purpose Valve Grease 250kg/DR](https://www.fl-sz.cn/en/products/rs-clare-claretech-hfl-special-purpose-valve-grease-250kg-dr) - [RS Clare Claretech HFL Special‑Purpose Valve Grease 18kg/DR](https://www.fl-sz.cn/en/products/rs-clare-claretech-hfl-special-purpose-valve-grease-18kg-dr) - [RS Clare Claretech HFL‑WG Low‑temperature Grease 18KG/Pail](https://www.fl-sz.cn/en/products/rs-clare-claretech-hfl-wg-low-temperature-grease-18kg-pail) - [RS‑Clare ClareTech Autolube MPM Fully‑Synthetic Extreme‑Pressure Grease, 12.5kg/Pail](https://www.fl-sz.cn/en/products/rs-clare-claretech-autolube-mpm-fully-synthetic-extreme-pressure-grease-12-5kg-pail) - [RS‑Clare ClareTech Valve Lubricant 601‑WGX Extreme Low‑Temperature Wellhead Valve Grease, 18kg/Pail](https://www.fl-sz.cn/en/products/rs-clare-claretech-valve-lubricant-601-wgx-extreme-low-temperature-wellhead-valve-grease-18kg-pail) - [RS‑Clare ClareTech Valve Sealant 701 Emergency Repair for Leaking Wellhead Valves, 18kg/Pail](https://www.fl-sz.cn/en/products/rs-clare-claretech-valve-sealant-701-emergency-repair-for-leaking-wellhead-valves-18kg-pail) ## Enquiries and technical support Send the operating conditions — temperature, speed, load, and whether there is food or pharmaceutical contact.
