🌟 Superior Sealing & Safety
-
ROHS Food-Grade Silicone: Manufactured from environmentally friendly, food-grade silicone. 100% non-toxic, odorless, and perfectly safe for sensitive marine reef tanks, freshwater aquaculture, and drinking water reservoirs.
-
Standard vs. Widened Design: Choose the "Standard Type" for regular slim fittings, or upgrade to the "Widened Type" which provides a massive surface contact area—ideal for securing slightly uneven drill holes, chipped glass edges, or extra-thick panels.

🚨 Sizing & Special Fitment Warning (Crucial!)
Our sizes are listed as: Inner Diameter (I.D) × Outer Diameter (O.D) × Thickness. Please read the Atradesen.com fitment rules carefully:
-
⚠️ 46mm & 58mm (1.5" / 2") RESTRICTION: Due to international thread standards, the gaskets with 46mm and 58mm inner diameters are designed to slip over MALE THREADS ONLY. They are NOT suitable for slipping directly over bare 50mm or 63mm PVC pipes! (All other sizes have no such restriction).
-
Measurement Tip: Always measure the precise Outer Diameter (O.D) of your bulkhead's male thread to select the correct gasket Inner Diameter (I.D).
