Wireline seals are precision elastomeric and thermoplastic components that maintain pressure control during slickline, braided line, and electric line operations. Designed for 5,000–30,000 psi and -50°F to 400°F, they prevent wellbore fluid escape while allowing smooth cable movement in grease injection heads, pack-off systems, and BOPs worldwide. https://globalsealstech.com/product-category/oil-gas-seals/oil-free-lubricated-pump-seals/
