Asc Engineered Solutions 390171320 Gruvlok Saddle Tee 4x3 in

Product Description

The ASC Engineered Solutions 390171320 is a Gruvlok grooved-end painted saddle tee with a female pipe thread (FPT) outlet, designed for use in grooved piping systems where a branch connection is required. Constructed from ductile iron, this fitting provides the structural integrity demanded in commercial and industrial piping applications. The saddle tee design allows a branch outlet to be added to an existing grooved pipe run without cutting out a full tee section. At 4 inches by 3 inches, it accommodates a 4-inch main line with a 3-inch FPT branch outlet. Installation is performed by licensed pipefitters and mechanical contractors familiar with grooved piping systems.

This saddle tee is suited for commercial mechanical systems including HVAC hydronic distribution, fire protection piping, and industrial process piping. The FPT outlet accepts standard threaded fittings or valves, making it adaptable for branch takeoffs in wet or dry systems. The painted exterior finish provides basic corrosion resistance during storage and installation. This fitting is appropriate for both new construction and retrofit applications where grooved-system infrastructure is already in place.

Key Features

• Ductile iron construction for high-strength performance in grooved piping systems
• 4-inch main line by 3-inch FPT branch outlet configuration
• Female pipe thread outlet accepts standard threaded components
• Painted exterior finish for basic corrosion protection
• Saddle tee design enables branch connections on existing grooved pipe runs

Compatibility

Designed as an OEM-style grooved saddle tee fitting for use in standard grooved piping systems with a 4-inch main pipe and a 3-inch threaded branch outlet.

Installation Notes

Installation should be performed by a licensed pipefitter or mechanical contractor in accordance with applicable mechanical codes and the grooved-fitting manufacturer's assembly instructions. Depressurize and drain the piping system fully before adding or modifying any fittings. Verify that the pipe end grooves conform to the required groove dimensions before assembly. Thread sealant or tape appropriate for the service fluid should be applied to the FPT connection before installing any threaded branch component.
