The new KQ2 range of products are lighter than previous models and have the advantage of improved insertion and removal forces. Can be used under a wide range of pressures from a low vacuum to 1MPa Low force required for fitting and removal Compact dimensions for use within smaller spaces Tube-to-Tube Fittings & Plugs Sealant coated threads minimise assembly time. The fittings can be used on vacuum or positive pressure lines. Suitable for use with nylon, soft nylon or polyurethane tube for compressed air or water (general industry) conveyance.
