Application:
T400757 is an exhaust-valve seat ring that is pressed into the cylinder heads of Perkins 1506A/E88TAG 6-cylinder diesels (8.8 L) as well as the 1004/1104 4-cylinder family (4.0–4.4 L) used in 150–250 kW generator sets, combine harvesters, MF 6400-series tractors and marine auxiliary engines. It provides the 45 ° sealing surface for 38 mm exhaust valves, maintaining blow-by below 1 % and keeping exhaust temperature within EU Stage IIIA limits after 12 000 h of full-load duty.
Technical specifications:
OD 46.0 mm, ID 38.5 mm, thickness 7.0 mm, seat angle 45 °, interference fit 0.06–0.10 mm in aluminium head, depth in pocket 7.5 mm. Material is low-carbon (0.15 %) steel billet that is copper-infiltrated and sintered to 7.2 g cm⁻³ density, giving 350 HB hardness and thermal conductivity 45 W m⁻¹ K⁻¹ for rapid heat rejection.
Material & performance features:
The copper-infiltrated matrix resists valve micro-welding and transfers heat away from the 21-4N stainless valve head, keeping seat temperature below 220 °C even when exhaust gas reaches 700 °C. Controlled 0.25 µm Ra surface finish beds in within 50 h, maintaining blow-by <1 % for the engine’s full life.
