Material: carbon steel to ASTM SA-234 Grade B, Concentric type: weld on, Dimensions conform to ASME B16.

Reducer 4-Inch to 2 1/2-Inch plus 5 Dust Collection Cone Reducer 4-Inch to 2 1/2-Inch plus 5

This tolerance may not apply in localized areas of formed fittings where increased wall thickness is required to meet design requirements of ASME B16.Pipe fitting adaptor which will let you convert the BSP (European) thread to NPT (American) standard thread. Unless otherwise specified by the purchaser, these tolerances apply to the nominal inside diameter, which equals the difference between the nominal outside diameter and twice the nominal wall thickness.

You would need to just screw this adaptor to existing female thread and you will end up with male NPT standard thread or other way round. Reduction connection - Application: for installation in water mains and central heating systems; - Size: 3/8" x 1/2" and 3/8" x 3/4"; - Thread type: Female x Male. Dimensional tolerances are in millimeters unless otherwise indicated and are equal ± except as noted.Available in a range of Tri-Clamp sizes, they have crevice- and pit-free interiors and are polished throughout. Female threaded reducing coupling muff for installation in water supply and central heating systems. Plumbing fittings come in various different types to reduce the flow size from larger to smaller or to change the direction of flow between two pieces of pipework.

4IN X 2IN SOCKET REDUCER 124.4.2:B | Wolseley

Threaded pipe reduction nipple fitting for installation in water supply and central heating systems. Manufactured from 316L grade stainless steel, PHP concentric reducers provide the perfect solution to connecting existing Tri-Clamp connections to newer or changing ones. BSP thread 1/2 Inch to NPT thread 1/2 Inch - threaded pipe fitting adaptor which will let you convert the BSP(UK) or G (European) thread to NPT American standard thread or other way round. MSS SP-43 only covers stainless steel buttweld fittings made for use with Schedule 5S and 10S pipe and Stub Ends suitable for use with Schedule 40S pipe, as defined in ASME B36. The dimensions and dimensional tolerances defined in MSS SP-43 are substantially the same as those in ASME B16.
