FAQs
Is Bedford 20-3677 a direct cross to the OEM kit?+
Yes. It’s produced as an aftermarket alternative referenced to OEM 237166. Confirm your sprayer’s parts diagram before purchase.
Do I need to soak the leather before installation?+
Briefly oil-soak the leather (per service manual guidance). This improves initial sealing and reduces break-in time.
When should I replace the rod or sleeve with the packings?+
Replace if you see scoring, pitting, or run-out. Damaged metal surfaces quickly ruin new leather packings.
Will this kit handle high-solids or solvent coatings?+
Leather performs well across many coatings. Always verify chemical compatibility with your material SDS and OEM guidelines.
How fast can this ship?+
If available, orders ship from Bedford Precision Parts (Bedford Hill, NY) with tracking and optional expedited methods.
