1/4 cup simple syrup
1 jalapeno pepper, halved and seeded
4 thin slices cucumber, or more to taste
4 wedges lime
2 tablespoons kosher salt, or as needed

Stir tequila, lime juice, orange liqueur, and simple syrup together in a pitcher with a lid; add jalapeno pepper and thin cucumber slices. Refrigerate at least 1 hour.
