Available in 1.1, 1.3, 1.5, and 2.0 BAR, each cap is precision-calibrated to maintain consistent system pressure and increase the boling margin of your coolant.\u003c\/p\u003e\n\u003cp\u003eType-A \"Mini\" Radiator Caps, for 32mm radiator necks Compatible with a wide range of OEM applications Stainless steel internals and body Silicon sealing is superior to OEM caps\u003c\/p\u003e\n\u003cp\u003eBy increasing system pressure, the coolant's boiling point rises, reducing the risk of localized boiling and maintaining heat transfer under load. Perfect match for the different available Coolant Expansion Tanks from Nuke Performance, as well as OEM replacement and custom installations.\u003c\/p\u003e\n\u003cp\u003eAvailable in different pressure ratings, ranging from 1.1 BAR to 2.0 BAR (16.0 PSI to 29.0 PSI). All with stainless steel internals and silicon sealing. The Type-A Radiator Caps from Nuke Performance are manufactured from stainless steel for long-lasting performance and durability. The seal is made of silicon instead of natural rubber found in OEM radiator caps, ensuring a greater life span and durability.\u003c\/p\u003e\n\u003cp\u003eThe stated pressure rating represents the nominal release pressure and operates within a defined tolerance range. The illustration above shows the intended operating range for each Nuke Performance radiator cap.\u003c\/p\u003e\n\u003cp\u003eCooling system pressure directly affects the coolant boiling point. Always select the lowest pressure cap that provides sufficient boiling margin for your application, as higher pressure increases thermal stability but also places greater stress on system components.\u003c\/p\u003e\n\u003cp\u003eHigher pressure raises the boiling point, reduces the risk of localized vapor formation, and improves thermal stability under high load. However, increased pressure also places greater stress on hoses, radiator, expansion tank, and seals. Available in several different pressure ratings, make sure to select the preferred one when placing an order.\u003c\/p\u003e\n\u003cp\u003eAlso compatible with select European vehicles and motorsport builds equipped with a Type-A (32mm) radiator neck.
