Cast-A-Seal 964 Open-Face Installation

August 15, 2019 0 Comment

A cast-in connector is similar to other boot type connectors with the exception of the installation procedure at the precast producer.

Many boot type connectors such as the PSX: Direct Drive or PSX: Nylo Drive are installed in cored or cast holes, whereas the Cast-A-Seal 964 is installed directly at the time of pouring the manhole.

This helps precast producers save time and money by eliminating a step during the production process.

Gary Jones, a veteran of Press-Seal covering the northeast of the United States as well as portions of northeast Canada, shows us how to assemble an open-face Cast-A-Seal 964.

How to Install the Cast-in Connector

Installing the cast-in connector requires very simple parts and no special tools. Essentially you’re going to assemble the cast-in connector with a:

  1. Gasket
  2. Mandrel
  3. Casting ring

In this video, Gary shows us how to install on a mandrel used for 48” manholes, noting that we do make mandrels for 60” manholes.

Begin by placing the arc side of the mandrel facing downward on a flat and stable surface like a table or on the floor of your precast facility.

Take the gasket and fold it inward on itself so that you create a smooth round surface that will easily slide down into the groove of the mandrel.

To ensure the gasket is installed correctly, the molded text on the gasket should be facing away or “up” away from the mandrel as seen in the video.

The bottom edge of the gasket is then easily slide inside the groove of the mandrel.

To finish the assembly, take the orange casting ring and align the negative notch in the ring to the positive notch in the mandrel.

Assembly is complete and you can attach to your form.

ASTM Standards and Where to use Cast-A-Seal 964

The Cast-A-Seal 964 meets or exceeds a variety of ASTM’s including, but not limited to:

  • ASTM C923 Standard Specification for Resilient Connectors Between Reinforced Concrete Manhole Structures, Pipes, and Laterals
  • ASTM C1244 Standard Test Method for Concrete Sewer Manholes by the Negative Air Pressure (Vacuum) Test
  • ASTM C1478 Standard Specification for Storm Drain Resilient Connectors Between Reinforced Concrete Storm Sewer Structures, Pipes and Laterals
  • ASTM C1644 Standard Specification for Resilient Connectors Between Reinforced Concrete On-Site Wastewater Tanks and Pipes

Not only is this cast-in connector meeting or exceeding high standards in quality and performance, it’s also a very versatile gasket that works with:

  • Manholes
  • Wet wells
  • Square pump and lift stations
  • On-site treatment structures

One of the primary benefits for the precast producer and the underground excavator is the use of CAS964 for grease traps, commercial septic tanks and similar structures.
