Midland Industries 46090A Self Piercing Needle Valve Kit

Product Description

The MIDLAND INDUSTRIES 46090A is a self-piercing needle valve kit designed for quick, no-solder tap connections on copper tubing. The kit includes a brass-body saddle valve with a solid pin operator and compression-style connection sized at 1/4 inch nominal. Technicians use it to add a low-flow branch line without cutting or sweating the existing line. At 0.24 pounds and with a compact footprint, the 46090A is a practical field solution for residential service work. Each unit is individually bagged for clean jobsite handling.

This valve kit is commonly installed in residential HVAC and plumbing applications where a small-diameter branch connection is needed off an existing copper supply line. Typical uses include humidifier feed lines, ice maker supply taps, and similar low-pressure, low-flow services. The compression fitting design allows a tool-ready connection without soldering equipment. The 7/16-24 thread size on the operator accommodates standard service tooling.

Compatibility

Designed as an OEM-style replacement or new-install saddle valve for residential copper tubing systems requiring a 1/4 inch nominal compression branch tap.

Installation Notes

Installation is performed by licensed plumbers or HVAC technicians following local plumbing codes and IPC guidelines. Shut off the water supply to the affected line before mounting the saddle clamp to prevent flow during installation. Ensure the saddle body seats flush against the tubing before advancing the piercing pin. Do not overtighten the compression fitting or the saddle clamp, as brass fittings can crack under excessive torque.
