90 degree right angle adapter - 1/4" BSP brass adapter.
Left hand thread form.
Although this fitting is intended for fuel gas we buy them having been cleaned to oxygen safe standard. This adapter comes with a left hand G1/4" BSP male thread to a loose left hand G1/4" BSP female nut.
This is a true gas fitting connection rather than something else. No PTFE is required as they should be brass on brass sealing.
