FAQ

What’s the difference between Rc and R?
Rc refers to internal tapered threads, while R refers to external BSPT threads.

How does the seal work?
The 1:16 taper creates a self-sealing fit without needing additional sealant, though thread tape can be added.

Can it be used for stainless steel?
Only conditionally – for INOX, a TiN or TiCN-coated version is recommended.

What does HSSE stand for?
High Speed Steel with cobalt for improved heat resistance and durability.

Can it be used manually?
Yes, but a machine setup provides more consistent precision.
