Features 1. Premium Material: This four-piece electric pressure cooker set is made of high-quality, durable silicone. Strong and durable with a long service life. Perfectly replaces old seals when they wear out or lose elasticity. 2. Easy to Operate: Simple to install, these seals fit securely into your electric pressure cooker, helping maintain optimal performance and keeping your appliance functioning like new. 3.

It is recommended to replace the sealing ring every 18 to 24 months, or immediately if deformation or wear is observed, to ensure proper operation. 5.
