Mission Rubber 0704 015 End Cap 4 Inch

Product Description

The MISSION RUBBER 0704 015 is a 4-inch rubber end cap designed to terminate drain, waste, and vent (DWV) pipe runs. It uses a compression-style band seal to create a leak-tight closure on the open end of a pipe without solvent cementing or threading. The rubber sleeve compresses against the pipe exterior when the stainless steel band clamp is tightened, forming a secure, watertight seal. Compatible pipe materials include cast iron, plastic, and steel, making this cap a versatile solution for multi-material piping systems. Licensed plumbers and pipefitters typically specify this fitting during new construction, remodeling, and system testing.

This end cap is used in residential and light commercial DWV systems where a pipe end must be permanently or temporarily capped. It is well suited for test-and-balance procedures where a pipe end needs to be sealed before a pressure or water test is performed. The 4-inch size fits standard 4-inch nominal pipe, which is a common trunk-line diameter in sanitary drain and building sewer applications. Installation does not require open flame, specialized adhesives, or pipe threading equipment.

Key Features

• Compression band-seal design eliminates solvent cementing and threading
• 4-inch nominal pipe size covers standard DWV trunk and building sewer lines
• Rubber sleeve provides a flexible, watertight closure
• Stainless steel band clamp resists corrosion in wet drain environments
• Domestically sourced product

Compatibility

Designed as an OEM-style replacement end cap for 4-inch cast iron, plastic, and steel DWV pipe systems. No specific model compatibility data was provided; verify nominal pipe outside diameter against Mission Band-Seal sizing charts before installation.

Installation Notes

Installation is performed by a licensed plumber following applicable IPC or local plumbing code requirements. Shut off all flow upstream and verify the pipe is dry and clean before sliding the end cap into position. Tighten the stainless steel band clamp with a nut driver or torque-controlled screwdriver to the manufacturer-specified engagement — do not over-tighten, as excess force can distort the rubber sleeve. Inspect the rubber sleeve for cuts or tears before installation; a damaged sleeve will not form a reliable seal.
