Product description
The Stainless Steel NPT Male × NPSM Female Swivel 45° Elbow is a 45° elbow in 316L stainless steel, forged from one piece. It carries an NPT male end and an NPSM female end. Stainless steel is chosen where corrosion rules out zinc-plated carbon steel: offshore and marine lines, chemical, fertiliser and petroleum plant, and food, beverage and pharmaceutical process equipment.
Construction
- Body: 45° elbow
- End 1: NPT male
- End 2: NPSM female swivel
- Material: 316L stainless steel, forged
Ends and sealing
- NPT: taper pipe thread that seals on the thread flanks, with sealant or tape; ASME B1.20.1.
- NPSM: straight pipe thread on a swivel nut that seals on a 30° seat, not on the thread; ASME B1.20.1.
Sizes
7 part numbers, 1/4" to 1-1/2". The Sizes & Part Numbers tab lists the size on each end, dimensions in millimetres and the Parker equivalent for every one.
- End 1: 1/4" NPT (1/4-18) to 1-1/2" NPT (1-1/2-11.5)
- End 2: 1/4" NPSM (1/4-18) to 1-1/2" NPSM (1-1/2-11.5)

Parker equivalents
For 5 of the 7 sizes the size table gives the Parker part number the manufacturer cross-references, so a part number taken off existing equipment can be matched to the Indus part number.
Carbon-steel version
The same configuration in zinc-plated carbon steel: Steel NPTF Male × NPSM Female Swivel 45° Elbow.
How to order
Quote the Indus part number from the size table. If you only have the fitting, send the thread or tube size on each end and the material, and Indus engineering will confirm the part number. Price and lead time are confirmed with the quotation.
