COMPATIBILITY
Compatible Equipment
This BK screw cap is engineered to fit Good Water Warehouse test tubes with standard threaded openings. It is designed as a direct replacement part for lost or damaged caps in Good Water testing kits. Ensure your test tube model requires the BK (black) cap variant before ordering, as Good Water may offer different cap colors for specific testing applications.
🔧 Keep spare caps on hand if you frequently perform water quality testing. Cross-threading can damage the cap or tube, so always align threads carefully before tightening.
