PVC/PTFE Injection Check Valve | 3/8-Inch OD x 1/2-Inch NPT

Pulsafeeder J41996 PVC/PTFE/Ceramic Injection Check Valve
The Pulsafeeder J41996 is an injection check valve assembly designed for compatible PULSAtron and CHEM-TECH chemical metering pumps. It combines a PVC housing, PTFE sealing components and a ceramic check ball with a 3/8-inch OD tubing connection and a 1/2-inch male NPT injection connection.
Injection Point Backflow Protection
Installed at the end of the chemical discharge tubing, the injection valve allows metered chemical to enter the process line while its check mechanism helps resist reverse movement of process liquid into the chemical feed system. This is especially important where the injection point is connected to a pressurized water or process line.

PTFE Seating and Ceramic Ball
The PTFE seat and ceramic ball distinguish J41996 from injection valves using elastomeric seats or stainless-steel check components. These materials must be selected according to the original pump wet end and the chemical being injected.
Installation at the Injection Point
The 3/8-inch OD tubing connection joins the metering pump discharge line, while the 1/2-inch male NPT fitting connects to the injection point. Confirm thread compatibility, tubing dimensions and the required injection arrangement before installation.
Maintenance and Inspection
Inspect the injection valve for deposits, damaged fittings and check-ball contamination. Chemical crystallization or accumulated debris may interfere with normal valve operation. Isolate the system and relieve pressure before servicing.
