Are plastic syringes resistant to high pressure?

In general, plastic syringes are not resistant to high pressure. Plastic syringes are usually made of materials such as polypropylene (PP) or polyethylene (PE), which have limited pressure resistance. Under high pressure, plastic syringes may deform, leak or rupture, leading to safety hazards.

For application scenarios such as high-pressure injection or liquid delivery, high-pressure resistant glass or metal syringes are generally used to better meet the demand. They have high pressure resistance and can withstand high pressure without deformation or rupture.

So, if you need to handle high-pressure liquids or perform operations such as high-pressure injections, it is recommended that you use syringes specifically designed for high-pressure use, and that you follow the relevant safety codes and operating guidelines during operation.
