During the assembly of high-purity gas and fluid delivery systems, conventional Face Seal-style fittings often experience rotary-action transfer, rotating the nut and the gland/gasket, leading to fitting failures. This is typically caused by the female nut losing its coating and inducing stainless-to-stainless contact, leading to many problems. Hy-Tech’s Anti-Torque Rings reduce or eliminate rotary action, preventing fitting malfunctions while elevating system performance. Our Anti-Torque Rings are cost-effective, safe, and easy to install.
Anti-Torque Rings
Our split-design Anti-Torque Rings can be utilized on both assembled and disassembled nuts.

Key Features and Benefits
Reduces or Eliminates Rotary Action
The low coefficient of friction helps eliminate rotary action transfer during assembly, preventing fitting bead damage caused by over-tightening and remakes.
Additionally, Hy-Tech Anti-Torque Rings prevent damage which requires the disassembly and reassembly of the fittings, saving time while reducing labor costs.
Interchangeable Sizes
Fits 1/4”, 3/8” (4-ATR-X-40), and 1/2” (8-ATR-X-40) fittings.
Versatility
Our Anti-Torque Rings can be used with assembled or disassembled male and female nuts.
Proprietary Coatings & Quality Materials
Our proprietary coating is extremely thin (.0001 – .0003 inches), ensuring the ring will not loosen the connection during fire or burnout. Our coating provides various additional benefits, including:
- Low friction
- High-temperature tolerance (effective up to 650 degrees Fahrenheit)
- Non-stick properties
Additionally, we utilize a 300 series stainless steel substrate, which is .005 inches thick with flexible properties for easy assembly.


Case Study/Technical Notes
For ¼” and ½” Fittings
Fact: When assembling Face Seal-style fittings, torque can be transferred to other parts like the gland and gasket.
Problem: This transfer of torque can cause several issues, including:
- Misalignment
- Tube twisting
- Gasket particulation
- Seal degradation
Solution: Hy-Tech Anti-Torque Ring
