Whether you’re capping exposed hydraulic fittings, protecting threaded rods during shipping, or just giving your workshop a cleaner look, these vinyl rubber thread cover caps get the job done. Sizes from tiny 1.5mm up to 24mm inner diameter — you’ll find the exact fit for bolts, pipe ends, valve stems, or flange studs. Made from durable rubber with a smooth, non‑slip surface, they resist wear, corrosion, and extreme conditions. Choose from black, red, white, clear, blue, yellow, or green. No more damaged threads or dusty open ports.
37 precise inner diameters – From Φ1.5mm to Φ24mm in 0.5mm increments (plus full mm steps). Find an exact match for metric bolts, tubing, and hydraulic fittings.
7 color options for easy identification – Black, red, white, clear, blue, yellow, and green. Use color coding to mark thread sizes or pressure lines at a glance.
Tough rubber material – High hardness combined with strong flexibility. Won’t crack under impact or tear during installation.
Smooth, shiny surface & uniform force distribution – No sharp edges to cut your fingers. The caps slide on easily and grip without slipping.
Wear‑resistant & corrosion‑resistant – Stands up to oil, moisture, dust, and mild chemicals. Ideal for garage, marine, agricultural, or industrial environments.
Multi‑purpose protection – Use on hydraulic pipe joints, transition fittings, oil cylinders, valves, flange studs, threaded rods, and even furniture feet for floor protection.
