Product description
The Stainless Steel ORFS Male × NPT Male Connector is a straight connector in stainless steel, forged from one piece. It carries a O-ring face seal (ORFS) male end and an NPT male 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: straight connector
- End 1: O-ring face seal (ORFS) male
- End 2: NPT male
- Material: stainless steel, forged
Ends and sealing
- O-ring face seal (ORFS): flat face sealed by an O-ring in a groove on the male face; SAE J1453 / ISO 8434-3.
- NPT: taper pipe thread that seals on the thread flanks, with sealant or tape; ASME B1.20.1.
Sizes
6 part numbers, 1/4" to 1". The Sizes & Part Numbers tab lists the size on each end and dimensions in millimetres for every one.
- End 1: 1/4" ORFS (9/16-18) to 1" ORFS (1-7/16-12)
- End 2: 1/4" NPT (1/4-18) to 1" NPT (1-11.5)
Pressure rating
The manufacturer publishes no pressure rating for this family. Tell us the working pressure your line sees and we will confirm the fitting is rated for it before you order.
Carbon-steel version
The same configuration in zinc-plated carbon steel: Male Connector m ORFS X m NPT.
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.
