Heater & Coolant Hose Connectors
Straight, elbow, tee and reducer connectors for heater and coolant hose, sized by the hose inside diameter they take. A connector is chosen by hose ID at both ends, not by the vehicle, so a 5/8 in straight and a 5/8 to 3/4 reducer are two different parts with two different jobs.

What decides the price
In order of impactGlass-filled nylon, PPS and aluminium behave differently at temperature and pressure. The material has to match what the original part was specified for.
A barbed end holds on a plain hose; a quick-connect end needs the matching clip. Mixing the two is how a hose comes off at temperature.
A reducer has two IDs. Both are stated, because ordering on the larger end leaves you with a loose fit on the smaller.
Worth checking before you order
Hose is sized by ID. Measuring the OD of a swollen hose gives a connector that will not seal.
Quick-connect clips fatigue. A new connector with an old clip is a comeback waiting for a hot day.

Questions
Do you know which connector my vehicle takes?+
Only from the OE number or a photo of the old part next to a ruler. The hose ID at both ends settles it.
Are the clips included?+
Quoted with or without. For quick-connect ends we recommend new clips every time.
Send the specification, not the product name.
Grade, size, thread standard and coating are what a quote is built from. A product name alone produces a price that changes twice before the order.
