The CD C&DV-CD3917 is a two-piece service kit that includes the CD3915 CRT pick and the CD3916 CRT thread chaser. Designed for trade professionals who service CRT-style valve and fitting connections, this kit bundles the two most commonly needed hand tools for cleaning and chasing threads on CRT fittings. The CD3915 pick allows technicians to clear debris and residue from CRT ports, while the CD3916 thread chaser restores thread integrity before reassembly. Keeping both tools on hand reduces callbacks and speeds up field service on CRT valve connections.
This kit is suited for plumbing, HVAC, and mechanical service technicians working on systems that use CRT-style fittings and valve connections. It is appropriate for both residential and light commercial service applications where CRT port maintenance is part of routine valve replacement or repair work. The included components are sold together as a matched set under the C&DV-CD3917 kit part number.
Designed for use with CRT-style valve and fitting connections requiring thread chasing and port pick service.
These tools are used by licensed plumbers, HVAC technicians, and mechanical service professionals during valve service or replacement. Before using on any pressurized system, shut off supply pressure and depressurize the line at the service point. Use the thread chaser with steady, even hand pressure to avoid cross-threading or damaging existing threads. Follow applicable local codes and manufacturer service procedures for the valve or fitting being serviced.
