Q&A

Please note, Pilotshop's personnel are not certified aircraft mechanics and can only provide general support and ideas, which should not be relied upon or implemented in lieu of consulting an A&P or other qualified technician. Pilotshop assumes no responsibility or liability for any issue or problem which may arise from any repair, modification or other work done from this knowledge base. Any product eligibility information provided here is based on general application guides and we recommend always referring to your specific aircraft parts manual, the parts manufacturer or consulting with a qualified mechanic.

Q: Regarding RA630365 copper exhaust gaskets: Are these used in pairs, where you would stack 2 for each flange, or just one per flange? So on a 4 cylinder engine, would I need 8, or 4 total?

Only one of the RA632837 gaskets are required per cylinder. The RA630365 have a raised bead that can be stacked if desired, but not required

Q: If using 2 gaskets per cylinder, do the raised beads oppose each other or should they interlock?

Make sure cylinder and exhaust stack flanges are flat. Check aircraft maintenance manual for proper installation. In most cases solid gaskets should be installed in pairs with raised beads interlocked and facing away from the cylinder. Also check maintenance manual for exhaust nut torque spec. Re-torque after a hot run.
