Choosing Pulsafeeder J41878 for a 3/8-Inch Chemical Injection Line
The Pulsafeeder J41878 is an FPP/PTFE/316 stainless steel injection check valve designed for a 1/4-inch ID by 3/8-inch OD tubing configuration. Its material combination and smaller tubing connection distinguish it from other PULSAtron injection valve assemblies.
Product Details at a Glance
- SKU: J41878
- Component: Injection Check Valve
- Body: FPP
- Seat: PTFE
- Check Ball: 316 Stainless Steel
- Tubing ID: 1/4 Inch

Correct Tubing Selection
The valve is identified for 3/8-inch outside-diameter discharge tubing. A similar valve, J41879, uses 1/2-inch OD tubing. Verify tubing dimensions rather than relying only on visual similarity.
One-Way Injection Function
The internal check mechanism helps prevent process liquid from flowing backward through the chemical injection line while allowing metered discharge into the process.
PTFE and Stainless Steel Materials
J41878 combines a PTFE valve seat with a 316 stainless steel check ball. The material selection should match the original pump specification and must be compatible with the chemical being handled.
Replacement Checklist
- Confirm the original injection valve part number.
- Measure the outside diameter of the discharge tubing.
- Verify the process-side connection.
- Check the condition of the valve seat and check ball.
- Relieve system pressure before servicing.
