T-H Marine AS-1 Aerator Screen/Strainer - 3/4"-14 Thread Aerator Pump Intake Fitting

The T-H Marine AS-1 is a screw-on aerator screen/strainer built to protect aerator pump intakes from fish scales, sludge, and other debris that can clog a livewell or baitwell system. It threads directly onto a 3/4"-14 aerator pump intake and is also the matched strainer for T-H Marine's THSM-1 and THSM-1XL thru-hull strainer mount fittings, which pass a 3/4" thru-hull passage through a transom or livewell wall. Because the AS-1 is threaded to fit the THSM-1/THSM-1XL mount, it seats flush against the wall on the intake side with no extra nut needed to secure it, giving a clean, low-profile installation whether the pump draws water through the transom or recirculates from the livewell.

Constructed from stainless steel wire mesh, the AS-1 is built to resist corrosion in continuous freshwater and saltwater service while keeping the pump's intake path clear. Installation is a simple screw-on operation with no special tools required, making it an easy upgrade or replacement part for anyone maintaining a livewell, baitwell, or washdown aeration setup. It is compatible with 3/4" hose connections, matching the thread and hose sizing used on the THSM-1 family of fittings.

Frequently Asked Questions

What is the T-H Marine AS-1 used for? The AS-1 is a screw-on aerator screen/strainer that threads onto a 3/4"-14 aerator pump intake to keep fish scales, sludge, and debris out of the pump, protecting livewell and baitwell aeration systems from clogs.

What thread size does the AS-1 aerator screen use? The AS-1 uses a 3/4"-14 thread, matching standard aerator pump intake fittings.

Does the AS-1 fit T-H Marine's thru-hull strainer mounts? Yes, the AS-1 is threaded to fit T-H Marine's THSM-1 and THSM-1XL thru-hull strainer mount fittings, seating flush against the mounting wall with no extra nut required.

What is the difference between the THSM-1 and THSM-1XL fittings the AS-1 works with? The THSM-1 has a 1-3/4" threaded section and 4" overall length, while the THSM-1XL has a 3" threaded section and 4-1/2" overall length for thicker surface installations; the AS-1 aerator screen threads onto either.

What material is the AS-1 aerator screen made from? The AS-1 is made from stainless steel wire mesh, chosen for corrosion resistance in both freshwater and saltwater use.

How much does the AS-1 aerator screen weigh? The AS-1 aerator screen/strainer weighs 0.1 pounds.

What size hose works with the AS-1 fitting? The AS-1 is compatible with 3/4" hose connections.

Is the AS-1 easy to install? Yes, the AS-1 is a screw-on strainer that threads directly onto a 3/4"-14 aerator pump intake or onto a THSM-1/THSM-1XL thru-hull mount, requiring no extra nut or special tools.

Can the AS-1 be used for both transom and livewell installations? Yes, when paired with a THSM-1 or THSM-1XL thru-hull mount, the AS-1 works for remote-mounted pumps filling from the transom or recirculating from the livewell.

How is the AS-1 different from T-H Marine's AS-2 or AS-6 screens? The AS-1 is sized for a 3/4"-14 thread pump intake, while T-H Marine's AS-2 fits a 1"-8 thread thru-hull fitting and the AS-6 fits a modified 1-1/2" thru-hull, so the correct screen depends on the intake or fitting thread size.

What comes with the AS-1? The AS-1 is the aerator screen/strainer component itself; the matching THSM-1 mount fitting is sold separately unless purchased as the THSM-1KIT, which bundles the mount and screen together.
