Larsen Supply Co., Inc. 03-1709 Shower Flange Nipple 6 Pack

Product Description

The LARSEN SUPPLY CO., INC. 03-1709 is a plastic universal shower flange nipple designed to seal the wall escutcheon around shower arm penetrations. The tapered sizing allows it to fit a range of rough-in openings without requiring an exact match to the original opening diameter. This part is sold in a carded package of 6 units, making it practical for stocking a service van or completing multiple shower repairs in one trip. Plumbers and plumbing service technicians install this component during shower valve service, trim replacement, or finish work where the wall flange needs a clean, watertight fit against the tile or wall surface.

This flange nipple is suited for residential shower applications where the arm exits the wall and the surrounding opening needs to be covered and sealed. The universal tapered design accommodates variations in wall opening size commonly encountered in retrofit and replacement work, reducing the need to carry multiple size-specific flanges. It is appropriate for standard residential shower arm installations in both new construction finish work and service replacement scenarios.

Key Features

• Tapered sizing accommodates a range of wall opening diameters for universal fitment
• Plastic construction resists corrosion in wet shower environments
• Carded retail packaging — 6 units per package for efficient stocking
• Lightweight at 0.26 pounds per package, easy to carry in quantity

Compatibility

Designed as an OEM-style replacement flange nipple for standard residential shower arm wall penetrations where a universal tapered fit is required.

Installation Notes

Installation is performed by a licensed plumber or experienced plumbing technician during shower trim or valve service. Shut off the water supply to the shower before beginning any work on the shower arm or valve trim. Slide the flange nipple over the shower arm before threading the arm into the drop-ell or fitting in the wall, as it cannot be installed after the arm is secured. Ensure the flange seats flush against the wall surface to provide a clean finish and prevent moisture intrusion behind the escutcheon.
