Ask A Question

Description & Features

Constructed from steel in a straight configuration, this male BSPP bulkhead fitting provides a same-size, same-thread connection on both ends, making it well suited for panel or wall pass-through installations in hydraulic systems. Both sides carry a G 1-1/4 - 11 thread designation at 1-1/4" nominal size, allowing consistent thread engagement across the connection.

The Mbspp-Mbspp Bulkhead 3" Long is an Adaptall product, measuring 76.9mm in overall length with a 50mm hex width on each side. The all-steel construction supports reliable performance in demanding industrial environments where bulkhead-mounted fittings are required to maintain secure, leak-resistant connections through a panel or enclosure wall.

Question by: Stan A on May 24, 2025, 10:06 AM
both ends are male BSPP on this thing, right? just want to make sure i'm not misreading the specs before i order
Answer by: Customer Support on May 26, 2025, 6:11 AM
Correct on both counts. Each side carries a G 1-1/4 - 11 male BSPP thread at 1-1/4" nominal size, so you're getting a straight same-size male-to-male connection all the way through. No reducers or adapters needed if your panel connections are already set up for that thread on both faces.

Is this thing solid steel all the way through? I need something that can take a beating.
Answer by: Customer Support on Jun 14, 2025, 8:20 AM
Yes, this bulkhead fitting is constructed entirely from steel, so it's well-suited for demanding industrial applications where you need a secure and leak-resistant connection through a panel or enclosure.

got a bulkhead pass-through job, is this one straight through with the same threads on both sides?
Answer by: Customer Support on May 19, 2025, 7:20 PM
For a clean panel or wall pass-through, it gives you a straight, same-size connection on both ends. Both sides are male BSPP with a G 1-1/4 - 11 thread callout, so thread engagement stays consistent from one side of the bulkhead to the other.
