波兰采购需求：登陆阀、减压阀、消防水带接头、喷射喷嘴、船用消火栓、消防设备

I hope this message finds you well. I'm reaching out to inquire about the availability of a specific size of storz coupling, particularly one that measures 76mm. Additionally, I'm interested in any reduction options you might have available to complement this coupling. I've attached a photo that highlights the required dimensions for your reference. Could you please provide information on availability, pricing, and lead times? Your prompt response would be greatly appreciated as I look to finalize my sourcing decisions soon. Thank you!
