Frequently asked questions
What is the difference between SAE Code 61 and Code 62 flanges?
SAE Code 61 flanges are rated for 3000 PSI working pressure and are the most common size. Code 62 flanges have a narrower face and thicker body, rated for 6000 PSI. The bolt-hole pattern is different between the two codes for the same bore size, so they are not interchangeable.
What port end options are available for SAE flange heads?
We offer SAE flange heads with DIN 24-degree cone, BSPP (G thread), NPT, ORFS, JIC 37-degree flare, and butt weld ends — as well as blank flanges for custom machining. Custom end configurations are available on request.
