Is this the same as PR4? Fisher site does not show any spr4

Yes, PR4 and SPR4 are the same refills and they work in most Fisher Space pens, NOT the Fisher Multi Function pen which uses a SU4F refill

What are the dimensions of the refill? I want to put it inside a pilot g2.

This is a Parker style refill and it measures 3 1/2" long without the Parker adapter.

is this listing for 1 or 3 refill? descprition does not say but picture is of 3.

3 refills as you see in the picture
