## Description

RS‑Clare ClareTech HFL‑WG is a low-temperature fully synthetic wellhead gate valve grease. Developed specifically for hydraulic fracturing operations and high water-cut well sites, it offers excellent pumpability at low temperatures and suits cold frac sites. Featuring a proprietary water-thickening formulation, it resists dilution and washout upon water contact and improves retention within valve cavities. It withstands fracturing fluids, water and condensate hydrocarbons, and blocks proppant/sand ingress into valve cavities. Formulated with extreme pressure and corrosion-inhibiting additives to extend relubrication intervals. Used for preventive maintenance of frac tree gate valves.

## Features

-Patented water-thickening technology: no thinning on water contact, slight thickening for enhanced valve cavity retention, anti-washout in high-water-cut service;

-Resists water, fracturing fluids, aliphatic hydrocarbons and condensate oil; contains corrosion inhibitors & EP additives for high-pressure valve protection;

-Field verified for ≥60-stage frac jobs with 100-mesh proppant; no on-site re-greasing, prevents sand ingress to safeguard gate plates and seats

-High viscosity & strong adhesion, stays in cavity under high pressure，offers lubrication plus auxiliary sealing;

-Temp range: -10 ℉ ~ 350 ℉ (-23℃ ~ 177℃). Ideal for hydraulic fracturing gate valves, high water-cut wells and water injection wellhead gate valves.
