Product Details
Plastic Expansion Tube JG/T 139 ETAG 020 is manufactured from PE or nylon. When a compatible screw is driven into the sleeve, the tube expands against the hole wall to form a mechanical anchor intended for light-load installations.
Suitable substrates include brick, concrete and gypsum board. Common applications are mounting decorative trim, light fixtures and cabinets. A range of diameters is available; select the tube size to match the screw shank for wood screws or self‑tapping screws.
Specify material (PE or nylon), tube diameter and recommended screw type when ordering to ensure correct pairing with the intended substrate and application.
