Female Nuts Performance

Precision-machined specifically for Ultra-Torr assemblies, this nut ensures repeatable vacuum seals even after multiple disconnections. It provides secure tube retention in demanding environments such as laboratory analysis and industrial vacuum processes.

Ultra-Torr Assemblies

Ultra-Torr fittings are designed for quick and reliable vacuum-tight seals on metal tubing without the need for tools beyond finger-tightening in many cases, although the nut ensures the final mechanical integrity of the seal.

Installation Note

Do not mix or interchange Swagelok products or components with those of other manufacturers to ensure system integrity and performance ratings.
