Romac 103-0937041 Stainless Steel Tapping Sleeve 8x8x4 in

Product Description

The ROMAC 103-0937041 is a flanged stainless steel tapping sleeve designed to create a branch connection on an existing pressurized main without requiring a full system shutdown. Built for reducing configurations, this sleeve fits 8-inch pipe and accepts a 4-inch tap, making it a standard choice for water distribution and municipal piping work. The pipe outside diameter range of 8.97 to 9.37 inches accommodates typical dimensional variation found in ductile iron and cast iron mains. Licensed plumbers and waterworks contractors install this fitting during live-main tapping operations, typically in conjunction with a tapping machine and gate valve.

This tapping sleeve is used in underground water distribution systems where a new service line or branch lateral must be added to an active main. The reducing outlet configuration — 8-inch main by 4-inch tap — suits residential service extensions, fire suppression branch feeds, and municipal infrastructure upgrades. The flanged end connection on the outlet provides a secure, standardized interface for attaching a tapping valve prior to drilling. Stainless steel construction makes it suitable for soil environments where corrosion resistance is a priority.

Key Features

• Stainless steel body provides corrosion resistance in buried and wet environments
• Flanged outlet connection for positive, leak-resistant valve attachment
• Fits 8-inch pipe with an outside diameter range of 8.97 to 9.37 inches
• Reducing tapping configuration: 8-inch main by 4-inch tap outlet
• Designed for live-main tapping without system depressurization

Compatibility

Designed as an OEM-style replacement and new-installation tapping sleeve for 8-inch water mains with an outside diameter falling between 8.97 and 9.37 inches, including typical ductile iron and cast iron pipe in that OD range.

Installation Notes

Installation must be performed by a licensed waterworks or plumbing contractor following applicable local codes and AWWA standards. Isolate and depressurize the branch side of the system as required before final connection; the main itself is typically tapped under pressure using an approved tapping machine. Verify pipe outside diameter with calipers before installation to confirm fit within the 8.97 to 9.37 inch range. Torque all fasteners evenly and in sequence per the fitting manufacturer's published guidelines for the specific bolt pattern.
