Frequently asked questions
Which FNPT thread sizes are available?+
Six: 1/4" (SKU 2TCX14F), 3/8" (2TCX38F), 3/4" (2TCX34F), 1" (2TCX1F), 1.5" (2TCX15F) and 2" (2TCX2F). Each is a separate variation with its own price.
Is there a 1/2" FNPT option?+
No. This cap is stocked in 1/4", 3/8", 3/4", 1", 1.5" and 2" only. The 2" tri-clamp to male NPT adapter is stocked in 1/2", so that is the alternative if a 1/2" thread is what you need.
What tri-clamp size does it fit?+
2" tri-clamp on every variation. Only the NPT thread size changes between variations.
Male or female thread?+
Female NPT (FNPT) — a male fitting screws into it. The male-threaded (MNPT) version of the same 2" cap is a separate listing.
What alloy is it?+
Our source data places this cap in the supplier's stainless steel tri-clamp range but does not record the alloy grade per variation. Ask us to confirm 304 or 316 in writing before ordering if your specification depends on it.
Are a clamp and gasket supplied?+
No. The item is the end cap and its welded adapter only. Clamps and gaskets are separate line items and can be added to the same quote.
