Will This Adapter Fit? — Quick Thread & Size Check
Before ordering, run through these five checks to confirm compatibility:
-
Side match — male vs. female: This adapter has a G (BSPP) female socket and an NPT male thread. Your existing G/BSPP fitting must be male; your NPT port must be female (internal threads).
-
Nominal size: Both ends are nominal 1 1/4". Verify the size stamped or listed on your existing fitting. G 1 1/4" and NPT 1 1/4" share the same nominal designation, so a 1 1/4" fixture on each side is what this adapter is designed for.
-
Thread family — G/BSPP (parallel) vs. NPT (tapered): G threads run parallel (constant diameter) and seal on a face/gasket. NPT threads are tapered and seal by thread engagement with thread tape or sealant. Do not confuse G with BSPT (tapered British threads) — BSPT tapers like NPT but uses a different pitch and will not mate correctly with NPT. If your fixture says BSP or G without a "T," it is parallel (G/BSPP) and is correct for this adapter's female side.
-
Sealing method:
-
G (BSPP) side: Use the included flat washer/gasket — do not apply thread tape to the parallel G threads. Tape on parallel threads does not provide a pressure seal; it just adds friction.
-
NPT side: Apply PTFE thread tape or pipe-thread sealant to the male NPT threads before threading into your female NPT port.
-
Common shower-arm question — G 1/2" fixtures on NPT shower arms: Many imported shower heads and body jets use G 1/2" (BSPP) male threads, while U.S. shower arms are typically 1/2" NPT female. These are different sizes from this 1 1/4" adapter. If you are adapting a G 1/2" shower fitting to a 1/2" NPT arm, you need a 1/2" G-to-NPT adapter, not this 1 1/4" unit. See our G-Thread to NPT compatibility guide for more on thread-family selection across sizes.
If all five checks pass, this adapter is your fit. If any check fails, please reach out before ordering — our team is happy to help identify the right fitting.
