Description
Brass in-line heater hose shutoff valve with a 5/8 in hose barb on one end and a 1/2 in male NPT thread on the other, used to isolate the heater core or auxiliary cooling circuit on heavy-duty trucks. Equivalent to industry-standard 404P-10-8 (Parker SV404P-10-8) truck valve. Brass construction handles coolant temperatures and pressures, with a quarter-turn lever for fast service shutoff.
