The 1-5/16"-12 threaded adapter fittings are compatible with 16AN ORB (O-ring boss) ports. Because the threads on these fittings are not used for sealing, PTFE paste or thread sealant is not required. The FKM O-ring should be lubricated. 

ORB ports are an industry standard and found on many automotive plumbing products, including most Radium products. All fittings include FKM O-rings.

	14-0698 The 16AN ORB male to 10AN ORB female coupler includes a preassembled FKM O-ring and requires a 16AN ORB (1-5/16"-12 threaded hole) with SAE chamfer to be drilled into the mating part for sealing.
	14-0699 The 16AN ORB with 1" Barb to 16AN Male Bulkhead Fitting was introduced in Radium Engineering FCST-X in 2023. It includes a preassembled FKM O-ring and requires a 16AN ORB (1-5/16"-12 threaded hole) with SAE chamfer to be drilled into the mating part for sealing.
	14-1194 The 16AN ORB to 3/4" Barb includes a preassembled FKM O-ring and requires a 16AN ORB (1-5/16"-12 threaded hole) with SAE chamfer to be drilled into the mating part for sealing.
