The Multiquip SR454A Vented Pipe Plug 3/8" is a genuine OEM component designed for STOW Diaphragm Pump (SDP-2) equipment. As a direct OEM replacement, it meets the exact material and dimensional specifications required for proper installation in the pump assembly. DHS Equipment sources this part directly through authorized Multiquip channels, so you can order with confidence knowing you are getting the correct part for your machine.
Key Features
- Genuine OEM Material Spec — Manufactured to the exact thread form and venting specification required for the SDP-2 pump assembly, ensuring a proper seal with controlled air passage.
- Direct-Fit Installation — Threaded 3/8" pipe size drops straight into the designated port on STOW Diaphragm Pumps with no machining or adaptation.
- SDP-2 Confirmed Fitment — Verified for STOW Diaphragm Pump SDP-2 series machines; use your model designation to confirm before ordering.
- Controlled Venting Function — The integrated vent feature allows pressure equalization in the pump housing, preventing vacuum lock and maintaining consistent diaphragm stroke performance.
- Fuel and Fluid System Compliance — On pump applications, a correctly functioning vented plug prevents pressure buildup that could compromise seals or cause fluid migration — making plug condition a genuine operational concern.
A vented pipe plug serves a dual role in a diaphragm pump: it closes off a threaded port in the pump housing while allowing controlled airflow through a small internal vent passage. This venting prevents pressure differentials from building up inside the pump chamber, which would otherwise resist diaphragm movement and reduce pumping efficiency. When a vented plug becomes clogged or is replaced with a solid plug, the pump can experience erratic stroke behavior, reduced output, or accelerated diaphragm wear.
