The Dresser 1 1/2″ Style 90 Insulated Restraining Coupling is a specialized plumbing and piping component used primarily in industrial and commercial systems to connect and secure pipes while providing electrical insulation. This coupling is designed to handle various applications, especially where electrical insulation and pipe alignment are crucial.

Product Specifications:

• Manufacturer: Dresser Industries
• Model: Style 90
• Size: 1 1/2″ diameter
• Type: Insulated Restraining Coupling
• Features: Includes a restraint system to prevent axial pipe movement, enhancing the stability and integrity of the pipe joint.

The time-proven Dresser Style 90 Coupling now offered in an insulating version. This coupling can be used to make quick pipe joints when positive
restraint AND electrical isolation are required. The Dresser Style 90 Insulated Restraining coupling joins steel to steel and steel to polyethylene pipes
listed in ASTM D2513.

Installation is Quick, Easy

Like the Style 90 fitting, the insulating coupling is easily installed using only a common pipe wrench. Pipe ends are stabbed without disassembling the coupling, thus reducing the risk of lost parts in the ditch. The Style 90 restraining couplings are rated for working pressures up to 150 PSI and a temperature range from -20 to +140°F.

Positive Pipe Restraint

The Style 90 restraining design creates a positive pipe restraint. As the installer tightens the nut, the gasket is compressed and the grip ring engages the pipe end creating a strong grip. This gripping action increases as internal pressure, thermal contraction of the pipe or other forces attempt to pull the pipe out of the coupling. Pipe joints made in accordance with the Dresser Style 90 Insulated Restraining installation instructions meet or exceed the requirements of DOT 192.281(e).

Electrical Isolation

Dresser Grade 41 gaskets and dielectric plastic components provide electrical isolation of the coupling from the pipe on which it is installed. These materials have been employed for many years in other Dresser natural gas products when electrical isolation is required.

Factory-applied Coatings

Style 90 Insulated Restraining couplings can be supplied with E-Coat or Plastisol coating, which offers quality no field coating can approach. Anode connectors can also be supplied, when required, for additional corrosion control.
