Pulsafeeder J41877 PVC/PTFE Injection Check Valve Assembly
The Pulsafeeder J41877 is a chemical injection check valve assembly listed for compatible PULSAtron metering pumps. It features a PVC construction with PTFE components and a 1/2-inch outside-diameter tubing connection.

Correct Tubing Size
The 1/2-inch tubing connection is an important distinction from J41996, which is listed for 3/8-inch OD tubing. Selecting the correct connection size helps match the original chemical feed line and avoids inappropriate substitutions.
PVC and PTFE Material Configuration
The PVC and PTFE construction must be evaluated for the chemical concentration, operating temperature and process conditions. Do not assume that all injection check valves with the same tubing size have identical wetted components.
Inspection and Service
Check for damaged connections, leaks, chemical deposits and restrictions at the injection point. If chemical feed performance becomes inconsistent, inspect the injection valve as part of the complete discharge-side troubleshooting procedure.
Installation Considerations
Confirm the original pump model, tubing dimensions and injection connection before installation. Follow the manufacturer instructions and depressurize the process line before removing the existing valve.
