Description

A 2″ tri-clamp end cap with a female NPT adapter welded into it. Per the supplier’s description the adapter is joined to the cap by a sanitary weld, giving a single fitting that takes a 2″ tri-clamp ferrule to threaded pipe.

Six thread sizes are stocked as separate variations. The tri-clamp face is 2″ on all of them.

  • 1/4″ FNPT — SKU 2TCX14F
  • 3/8″ FNPT — SKU 2TCX38F
  • 3/4″ FNPT — SKU 2TCX34F
  • 1″ FNPT — SKU 2TCX1F
  • 1.5″ FNPT — SKU 2TCX15F
  • 2″ FNPT — SKU 2TCX2F

There is no 1/2″ FNPT variation on this cap. If you need 1/2″, check the male-thread listing, which is stocked in that size.

The clamp and gasket for the 2″ joint are separate line items and are not included with the cap.

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.
