The longer, tapered plug design of Precision Seal septa fits

standard taper joints precisely providing a sealing surface

that is 50 to 80% higher than standard sleeve stoppers.

The inner seal design of Precision Seal septa minimizes

chemical and solvent vapor migration up the joint to the

sleeve which can swell, leak, or fail from exposure. The

surface texture of the rubber is similar to that of a ground

glass joint and resists movement once seated.

Precision Seals are made using a certified natural rubber

formulation for superior resealability during use.

SAFETY ADVICE—The Precision Seal flexible sleeve must be secured to the glass joint

with a Wrap-It Tie or similar device during cannulation and for applications that involve

pressure. DO NOT rely on the sleeve alone to anchor the septum. This rule applies to all

types of rubber septa that are used for critical applications.
