Stainless Steel Pipe Fittings
Pipe – Pipe Swivel
OmegaOne manufactures stainless steel pipe fittings and adapters made to the NPTF (National Pipe Thread Fuel) and NPSM (National Pile Straight Mechanical) standards defined by ANSI B 1.20.3 and SAE Straight Thread fittings as defined by SAE J514. Standard NPT/F pipe fittings are the most basic level of thread connection. All hose barb and push-on style hose fittings are manufactured from 316 Stainless Steel.
Pipe fittings and adapters use a tapered thread connection to form a mechanical seal. The seal is formed as the male and female threads are tightened together forming a dry seal. The thread angle on an NPT and NPTF thread is 60° that has flattened peaks and valleys which is referred to as a Sellers form. OmegaOne manufactures to the NPTF standard, which is designed to seal better than NPT.
Standard pipe threads offer the most basic connection and are still widely used. Pipe fittings are ideal where systems require high pressure and high temperatures. There are many limitations with pipe fittings. It is not recommended that these fittings be repeatedly assembled and disassembled. The threads are not designed for repetitious use and are not as durable when there is a lot of vibration in the system. Pipe fittings do not allow for adjustability that straight thread fittings offer.
SAE straight thread fittings, also referred to as O-Ring Boss (ORB) is defined by SAE J514. These fittings have parallel threads and use an O-ring to completely seal. The seal of the fitting occurs when the O-ring is compressed during tightening. Parallel thread fittings are more common than taper thread fittings. Elbow and tee fittings are manufactured with an adjustable bulkhead nut, allowing the fitting position to be adjusted directionally during installation.
Straight thread fittings offer better reusability because they can be removed to service the system and then easily reinstalled. When removing and reassembling a straight thread fitting replacing the O-ring is recommended to ensure the integrity of the fitting in the system. Straight thread fittings perform better in systems with higher vibration than pipe thread fittings.
Pipe Swivel (NPSM)
The NPSM is a female pipe swivel fitting using a parallel thread to guide a seal on a 30° cone inside the swivel nut creating a metal-to-metal seal. The NPSM swivel is designed to mate only with any NPT or NPTF pipe thread fitting as long as the male thread has a 30° champher on the ID of the thread. OmegaOne manufactures our pipe thread fittings with the mating champher to ensure the universal usability of our taper pipe thread fittings.
OmegaOne carries an extensive inventory of standard and non-standard stainless steel pipe fittings (P series stainless steel fittings). We carry common sizes and configurations as well as uncommon “jump” sizes. In addition, OmegaOne carries NPSM, stainless steel pipe swivel fittings (PS series pipe fitting), and stainless steel hose barb, “push-on” style fittings (PL Series fittings).
