Conventional water-glycol fluids can form sticky, high-viscosity black residues containing metal fines under certain operating conditions — residues that can deposit around sealing elements and accumulate in anti-recoil valve internals, creating a critical system failure risk. HOUGHTO-SAFE® NL1 has been specifically formulated to minimise such residue formation and maintain stable pH over a 5-year service period — validated in long-term OEM cylinder tests.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures \u0026amp; Benefits\u003c\/h3\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;margin:16px 0\"\u003e\n  \u003cthead\u003e\u003ctr
