Hyster Forklift Radiator Cap 1637879 / 20995-401 — Metal
This metal radiator cap (part numbers 1637879 and 20995-401) is an OEM-quality replacement for Hyster forklift cooling systems. The all-metal construction provides superior durability compared to plastic-topped caps that crack from heat cycling and UV exposure in outdoor forklift applications. CE and ISO 9001 certified manufacturing ensures consistent pressure rating, spring tension, and seal quality across production batches.
The MANON brand cap ships in a carton box with 7-15 day delivery from China. Backed by a 3-month warranty. The dual part numbers (1637879 and 20995-401) cross-reference to multiple Hyster forklift models and series. Always pressure-test a new radiator cap before installation — even new caps can have manufacturing defects that prevent them from holding rated pressure.
