Can the Quick coupling plug with GW BSPT, NITTO KOHKI HI CUPLA, stainless steel AISI 304 be used in my water system if the medium must flow from socket to plug?

Yes . the Quick coupling plug with GW BSPT, NITTO KOHKI HI CUPLA, stainless steel AISI 304 can be used in your water system provided the fluid direction is from socket to plug. The HI CUPLA plug is explicitly described as a plug without valve and notes that âthe medium must flow from the socket to the plug,â so install it so flow enters the socket side first. It is designed for water installations, made of AISI 304 stainless steel, rated to 15 bar working pressure and offers the given flow capacities at 5 bar (1â³: 4000 l/min, 3/4â³: 3200 l/min, 1/2â³: 2600 l/min, 3/8â³: 1600 l/min, 1/4â³: 1000 l/min). Ensure thread compatibility (GW BSPT internal thread) and that your system pressure and required flow do not exceed these ratings.

Is the Quick coupling plug with GW BSPT, NITTO KOHKI HI CUPLA, stainless steel AISI 304 suitable if my system requires flow from socket to plug?

Yes - Quick coupling plug with GW BSPT, NITTO KOHKI HI CUPLA, stainless steel AISI 304 is suitable if your system requires flow from socket to plug. The product description explicitly states the medium must flow from the socket to the plug. It is designed for water installations, made of AISI 304 stainless steel, rated to 15 bar working pressure, and provides the listed flow rates at 5 bar (4000 l/min for 1â³, 3200 l/min for 3/4â³, 2600 l/min for 1/2â³, 1600 l/min for 3/8â³, 1000 l/min for 1/4â³). Ensure your inlet/outlet sizing and pressure match these specifications.
