Boshart pvcia-1012 Pvc Insert Adapter 1 X 1-1/4 Inch Mpt

Product Description

The BOSHART pvcia-1012 is a PVC insert adapter fitting that connects a 1 inch male pipe thread (MPT) to a 1-1/4 inch insert barb. It is designed for use in pressurized water distribution lines where a threaded pipe or valve outlet must transition to insert-style poly tubing. PVC construction makes this fitting tough, rigid, and resistant to a wide range of chemicals encountered in irrigation and water supply work. The material is also unaffected by ultraviolet exposure, making it suitable for above-ground and direct-sun installations without degradation over time.

This adapter is commonly installed in residential, commercial, and industrial irrigation systems. It is a practical choice for surface-run or shallow lines where burial below the frost line is not required. The rigidity of PVC means that if residual water freezes inside the line, ice pressure is relieved lengthwise rather than radially, reducing the risk of fitting failure. Plumbers and irrigation contractors use this fitting when transitioning from threaded metal or PVC pipe to poly tubing in drip, spray, or mainline distribution layouts.

Key Features

• 1 inch MPT x 1-1/4 inch insert connection for direct poly tubing attachment
• Rigid PVC construction resists chemicals and physical stress
• UV-stable material rated for direct sun exposure without shielding
• Freeze-resistant geometry directs ice expansion lengthwise, preserving the seal
• Suitable for residential, commercial, and industrial irrigation applications

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-1/4 inch insert poly tubing systems with 1 inch MPT threaded pipe connections in standard irrigation and water distribution assemblies. Industry number 1436-132.

Installation Notes

Installation is performed by licensed plumbers or qualified irrigation technicians. Shut off and depressurize the water supply line before cutting or threading any connections. Hand-tighten the MPT connection first, then apply a wrench for final seating — do not overtighten, as PVC threads can crack under excessive torque. Follow local plumbing code and applicable IPC guidelines for thread sealant use on plastic fittings.
