## Before you buy

- The listing also describes this tee as a compression union connector and gives a second size in its description as 5/16" OD x 1/4" MNPT x 5/16" OD, while the title and size field specify 1/4" NPT male. Confirm the required branch thread and fitting configuration before purchase. The stated pressure and temperature limits are manufacturer claims. NPT dimensions are nominal, not actual diameter.

## A good fit for

- Buyers connecting two 5/16-inch OD tubes to a 1/4-inch NPT male branch, after confirming the thread and fitting arrangement.
- Applications matching the listing's stated fuel, air, liquid, oil, gas or vacuum line uses and operating limits.

## Less suited to

- Buyers whose tubing OD, thread type or branch size does not match the listed connections.
- Systems requiring verified compatibility or pressure and temperature performance beyond the stated listing claims.

## Customer feedback

Aggregate ratings lean positive, with ratings in the four- and five-star categories, but the sample is small and no written feedback is supplied. The ratings do not identify customer experiences with fit, sealing or the stated operating limits, so they offer little guidance on compatibility beyond checking the listed dimensions.
