From tiny M1.3 screws up to 114mm industrial pipes — this rubber thread cover cap series has you covered. Whether you’re protecting hydraulic fittings, capping valve stems, or keeping dust out of large flange studs during storage, these vinyl rubber caps provide a snug, secure fit. Choose from black or red, both offering excellent wear resistance and corrosion protection. The smooth inner surface slides on easily without damaging threads, and the tough rubber stands up to oil, moisture, and extreme shop conditions. No more lost caps or mismatched sizes.
Massive size selection – over 100 inner diameters – From 1.3mm up to 114mm, including half‑millimeter steps in the small range and full mm from 10mm to 114mm. Find exactly what you need for metric hardware.
Two classic colors: black & red – Black for general protection, red for high‑visibility safety marking or identifying critical threads.
High hardness + strong toughness – Sturdy enough to resist tears, yet flexible enough to conform to irregular thread profiles without cracking.
Smooth, shiny surface & non‑slip grip – Uniform force distribution means no weak spots. The caps stay put but come off easily when you need them.
Wear & corrosion resistant – Formulated for harsh environments. Resists hydraulic oil, water, dust, and mild chemicals. Extends the life of your threaded components.
Multi‑purpose application – Perfect for hydraulic pipe joints, transition fittings, oil cylinders, valves, flange studs, threaded rods, bar ends, and even furniture feet or tube openings.
