The CAMPBELL map4 is a 1-inch PVC insert adapter configured with an insert x male thread end style, designed to create secure transitions between barbed insert connections and standard male-threaded fittings. This fitting is suited for use in flexible piping and polyethylene piping systems where a reliable mechanical connection is required. At 2.7 inches in length, it provides a compact transition point without adding excessive bulk to the assembly. Licensed plumbers and irrigation technicians install this type of adapter in pressure-rated plumbing lines, water service applications, and fluid distribution systems where barbed and threaded components must interface cleanly.
The map4 insert adapter is appropriate for residential and light commercial plumbing installations involving flexible polyethylene pipe, irrigation mainlines, or water distribution runs that require a transition to threaded fittings. Both the insert side and the male thread side are sized at 1 inch, making this a straight-size adapter with no reduction. It is a practical component in systems where polyethylene tubing terminates at a threaded valve, manifold, or fixture connection.
Designed as an OEM-style replacement or standard insert adapter fitting for 1-inch flexible polyethylene or compatible plastic piping systems requiring a male-threaded outlet connection.
Installation is typically performed by a licensed plumber or irrigation technician. Shut off the water supply and depressurize the line before working on the connection. The insert end should be fully seated into the pipe and secured with an appropriate clamp to maintain a leak-free seal under pressure. Follow local plumbing codes and the pipe manufacturer guidelines for torque and clamping requirements on the threaded side.
