Learn how to attach, sip, and straw-drink with the Cruiser Lid on a 40oz CORKCICLE tumbler, plus fit and leakproof tips.

Quick answer

To use a Cruiser Lid on a 40oz CORKCICLE tumbler, align the lid with the cup's threads, twist clockwise until snug, then choose sip or straw mode by rotating the spout. It fits standard 40oz Cruiser tumblers, but it is not leakproof, so avoid tipping it over.

Why the Cruiser Lid works on 40oz tumblers

The Cruiser Lid is designed for CORKCICLE's 40oz Cruiser tumblers, which share the same thread size as the 40oz Tumbler. That means you can swap lids between these models without a special adapter.

This lid gives you two ways to drink: a sip opening for hot or cold beverages and a straw slot for the included high-flow Tritan straw. The dual function makes it a versatile upgrade if you own multiple 40oz cups.

Leakproof? Know the limits

The Cruiser Lid is not leakproof. The sip opening and straw slot are open when not in use, so liquid can spill if the cup tips over. For travel or throwing the tumbler in a bag, consider a leakproof lid instead.

Also, the lid is a Final Sale item, meaning it cannot be exchanged or returned. Double-check that your cup is a standard 40oz CORKCICLE before purchasing.

Using the Cruiser Lid step by step

Check compatibility: Confirm your tumbler is a 40oz CORKCICLE Cruiser or 40oz Tumbler. The lid threads match these models. If you have a different size, the lid won't fit. Measure the mouth diameter if unsure; the lid is designed for 40oz only.
Attach the lid: Place the lid on top of the cup, aligning the threads. Twist clockwise until snug. Avoid over-tightening, which can crack the lid or strip the threads. A snug fit is enough; you should not force it.
Choose your drinking mode: Rotate the spout to align the sip opening with the cup's handle (or your preferred position) for sipping. For straw use, rotate to the straw slot and insert the included Tritan straw. Make sure the straw is fully seated to avoid it popping out.
Test for leaks: Before filling, tilt the cup slightly to check if liquid escapes from the openings. Since the lid is not leakproof, keep the cup upright when carrying it. If you need a leakproof option, look for a dedicated leakproof lid.
