Product Description

The PPS 691514197630 is a galvanized carbon steel nut, bolt, and washer set sized for 4-inch press fitting adapter flange applications. Each set includes one bolt, one nut, and one washer — all the hardware needed to secure a ProPress XL adapter flange connection. The galvanized finish provides corrosion resistance in wet mechanical environments. Rated to 200 psi and a temperature range of 0 to 250 degrees F, this hardware set is appropriate for the pressure and thermal demands common in commercial and residential hydronic and plumbing piping systems. Installation is handled by licensed plumbers and pipefitters working with press-fit systems.

This bolt set is designed for use with 4-inch Viega ProPress XL adapter flange applications. It is specifically called out for use with Viega ProPress XL Adapter Flange part numbers 81075 and 86077. Typical install scenarios include large-diameter press fitting connections in commercial plumbing, mechanical rooms, and hydronic heating systems where flanged adapter joints require dedicated fastener hardware.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter familiar with press fitting systems and flange connection procedures.

Inspect all hardware for damage before installation and do not reuse previously torqued fasteners.
