Buying replacement closures can feel like a split decision because the products serve different sides of the same idea: keeping containers sealed. One option is aimed at Luer connectors and dispensing needle accessories, while the other is aimed at the top of a salt or pepper shaker. These two options are not interchangeable, but each fits a clear use. The decision comes down to pack size, material, and what you actually need to cap.
Quick verdict
Choose the 150 Pack Sterile Luer Stopper Closing Cones if you are capping Luer connectors, dispensing needles, or other compatible fittings in bulk. Choose the 21 Pcs Pepper Cork Replaceable Salt Shaker Stoppers if you are refreshing kitchen shakers and want a lower-priced set. The price gap between the two listings is $20.09, and the count difference reinforces the split: one is a bulk pack, the other is a smaller set. Both are in new condition, so the decision comes down to fit and quantity.

Product notes
#### 150 Pack Sterile Luer Stopper Closing Cones - Dual Male/Female Replacement Caps
This is the higher-priced option and the one to reach for when you need a large supply of Luer-style closures. It comes with 150 caps designed for dual male and female Luer connectors. Each cap measures 0.72 x 0.39 inches and is made from PE. The caps are individually sterile-packaged and can withstand up to 300 kPa internal pressure, which makes them practical for dispensing needles and accessories. The tool-free connection keeps the capping process quick, which is a useful feature when you are working through several caps in a row. The trade-off is the upfront cost, plus the fact that 150 caps may be more than a casual user needs. If you only need a few closures occasionally, this pack may leave you with more inventory than you can use.
#### 21 Pcs Pepper Cork Replaceable Salt Shaker Stoppers Replacement Bottle
This is the lower-priced option and the one for kitchen shaker duty. It includes 21 stoppers in white, made of silicone, with an item diameter of 1.60 inches and a height of 1.00 inch. The title points to replaceable pepper cork salt shaker stoppers, so it is built for refreshing the tops of salt and pepper shakers. The 21-piece count is enough to handle several shakers or keep spares on hand. The clear limitation is that its purpose is kitchen shaker stoppers, not Luer connectors or dispensing needles, so it cannot replace the 150-pack in that kind of work. If you need Luer-style closures, this set does not match that application.
Final choice by use case
Pick the 150 Pack Sterile Luer Stopper Closing Cones for Luer-style capping projects where a high-count pack matters and you want individually sterile-packaged caps. Pick the 21 Pcs Pepper Cork Replaceable Salt Shaker Stoppers for shaker-top refreshment and kitchen use. If you frequently cap multiple Luer fittings in one session, the 150-pack will see you through many tasks. If you are simply switching out shaker tops, the 21-pack keeps the purchase small and focused.
