Overview:
The Plug PT3/8 Screw for Yanmar Engines (OEM No. 23876-030000) is a genuine Yanmar sealing plug for threaded service ports on the engine. Built from durable metal, it uses a PT 3/8 in tapered pipe thread (BSPT equivalent), with an approximate 16.66 mm major diameter, to create a tight, leak-resistant fit.
