Value Collection 13140 Malleable Iron Pipe Union 3/8 in 5 Pack

Product Description

The VALUE COLLECTION 13140 is a malleable iron threaded pipe union sized at 3/8 inch, designed to join two sections of pipe while allowing easy disconnection for maintenance or repair. Rated at 300 psi for liquid and gas service and 150 psi for steam, this Class 150 fitting carries a galvanized finish that provides corrosion resistance in demanding environments. It is a standard workhorse fitting used by plumbers, pipefitters, and HVAC technicians wherever a break-apart connection is required in a threaded iron pipe system. Each order includes five unions.

This union fitting is suited for residential and light commercial piping systems carrying water, gas, steam, or other compatible media within its pressure ratings. Typical install scenarios include gas supply lines, hydronic heating piping, compressed air distribution, and general-purpose plumbing where future serviceability of the joint is needed. The galvanized coating makes it appropriate for both indoor and moderately corrosive environments. Supplied in a pack of five, it is a practical choice for service trucks and shop inventory.

Installation Notes

Installation of threaded pipe unions is typically performed by a licensed plumber or pipefitter. Shut off and depressurize the line completely before disassembling or installing any union fitting. Apply an appropriate thread sealant or PTFE tape to all male threads per the applicable piping code, such as the International Plumbing Code or International Fuel Gas Code, before making up the joint. Do not over-tighten; use proper pipe wrenches and follow accepted trade practice for malleable iron fittings.
