Part of GRACO’s surge tank family that includes high volume in-line configurations (238986, 238987, 238988) and medium volume tee configuration (233736). Designed to work with pump systems to provide consistent material delivery. Maximum flow rates are recommended maximums for peak performance. Exceeding these values reduces the surge tank’s ability to dampen pulsation. Compatible with floor stand kit 218742 for support. This is an in-line surge suppressor with wetted parts including Carbine, SST, UHMWPE, Viton, and PTFE materials
