Let's explore this with Baoxing. Recommended model: BX-455/C-WY Baoxing Food-Grade Waterproof Grease.

How to choose the right lubricant for ceramic valve cores to prevent leakage and ensure smooth operation

Have you noticed that your home faucet becomes stiff and squeaky after prolonged use, and leaks frequently? The sealing rings of faucets in bathrooms and water purification equipment are constantly exposed to alternating hot and cold water and the erosion of acidic and alkaline water quality. 

The failure of sealing and lubrication not only affects the user experience but also poses safety risks as ordinary lubricants may release harmful substances, contaminating drinking water. Choosing the wrong lubricant can even cause the sealing ring to expand and corrode, increasing maintenance and replacement costs, making it a bad investment. 

In response to the pain points of sealing and lubrication of faucet sealing rings, Baoxing has specially launched the BX-455/C-WY food-grade waterproof sealing grease, custom-made for water-related scenarios such as bathrooms and water purification. 

With four core advantages, it provides a one-stop solution to problems such as seal failure, unsafe water use, and easy wear of sealing rings. It offers all-round and long-lasting protection for faucet sealing rings, balancing safety and durability, and providing professional lubrication protection for bathroom products. 

BX-455/C-WY Baoxing food-grade waterproof sealant grease has passed the strict standards of NSF H1, WRAS water certification, FDA and USDA in the United States. It is non-toxic, odorless and free of harmful substances, ensuring the safety of drinking water.

 It has strong water resistance and sufficient adhesion, effectively preventing water leakage and reducing maintenance troubles. It can withstand the alternation of hot and cold water and acid and alkali erosion, with stable performance at high and low temperatures. It is suitable for multiple scenarios and can extend the service life of sealing rings. 

At the same time, it reduces component friction, eliminates jamming and abnormal noise, is compatible with multiple materials without corrosion, and significantly reduces maintenance and replacement costs. 

The BX-455/C-WY food-grade waterproof sealant grease can directly replace Molik 111 without changing the original assembly process. It has full compatibility and perfectly matches all application scenarios and performance requirements of Molik 111. Moreover, it has been upgraded and optimized in terms of water safety and sealing durability. 

It can be quickly put into use without additional debugging, significantly reducing the cost and time for product replacement. 


Compared with Molik 111, the Baostar BX-455/C-WY food-grade waterproof sealant has more core competitiveness: its cost performance far exceeds that of similar products, effectively reducing the cost of bulk purchases and easing the financial burden on enterprises; relying on the advantage of localized production, the delivery cycle is short, completely solving the problem of production and maintenance stagnation caused by delayed supply; it has more comprehensive food-grade certification, making water contact use more reassuring. Currently, Baostar has reached a deep cooperation with JOMOO, adapting to its bathroom products, and truly achieving a balance of practicality, economy and safety for JOMOO. 

Baoxing has been deeply engaged in the field of special lubrication for 20 years, possessing mature production technology and a complete service system. We support sample testing and technical selection, and provide professional technical guidance throughout the process to solve all kinds of questions in the lubrication process of faucet sealing rings.
