T-H Marine

<h3>About T-H Marine Supplies</h3><p><strong>T-H Marine Supplies</strong> has been one of the most trusted names in the marine accessories industry for over five decades. <a href="/7603-t-h-marine">Founded in 1975 by Bill Huntley in Huntsville, Alabama</a>, the company grew from a small, family-owned operation into a leading manufacturer of boat parts and accessories serving both OEM boatbuilders and the aftermarket. Today, T-H Marine is a proud member of the OneWater Marine family, yet retains the hands-on dedication to quality that has defined it from the beginning.</p><h3>Designed by Boaters, for Boaters</h3><p>What sets T-H Marine apart is its roots. The team behind the brand has always been made up of avid boaters and anglers who understand the demands of real time on the water. That real-world perspective drives an approach to product development centered on practical innovation — solving problems that boaters actually encounter. From pioneering the first commercially available jack plate with the iconic <strong>HI-JACKER</strong>, to patenting improved throttle designs and narrow battery trays, T-H Marine has a long track record of bringing genuinely useful ideas to market.</p><p>Their <strong>ATLAS hydraulic jack plate</strong> became the dominant choice among professional bass fishermen and OEM boatbuilders alike. By the 2014 BASSMASTER Classic, ATLAS jack plates were found on the overwhelming majority of boats running hydraulic jack plates — a testament to the product's reliability and performance credentials.</p><h3>A Comprehensive Marine Product Lineup</h3><p>T-H Marine's catalog spans virtually every system on a modern recreational boat. Their product categories include jack plates, <a href="/7603-t-h-marine-trim-and-tilt-units-202681">trim and tilt units</a>, trolling motor accessories, plumbing and drains, LED lighting, hatches and deck plates, livewell aeration systems, rigging accessories, battery trays, and rod storage solutions. Whether you're rigging a tournament bass boat or fitting out a pontoon for family outings, T-H Marine likely has a product engineered for the task.</p><p>The brand supplies products to virtually every recreational boat manufacturer in the United States — found on bass boats, pontoon boats, runabouts, ski boats, offshore fishing boats, flats boats, aluminum fishing boats, and center console boats. Their aftermarket parts are available through marine dealers, retail chains, and online retailers nationwide.</p><h3>Innovation With a Proven Track Record</h3><p>Throughout their history, T-H Marine has continued to expand into new product niches while maintaining leadership in core categories. They introduced the first remote livewell drain valve, developed pioneering rod storage tube systems for boat compartments, and grew their lighting line to include waterproof courtesy and livewell lighting. Their <a href="/7603-t-h-marine-trim-and-tilt-units-201108">CMC tilt and trim systems</a> represent the same durability-first philosophy — built to handle the rigors of fresh and saltwater use over thousands of hours of operation.</p><p>With over 700 products in their lineup and a half-century of marine industry expertise, T-H Marine remains a go-to source for boaters who demand aftermarket accessories that match or exceed OEM standards.</p>

Product Details

The T-H Marine ILS1500DP is an inline scupper valve designed to prevent water backflow in marine drainage systems. This essential deck hardware component features a double barb configuration for secure hose attachment on both ends, making it ideal for kayaks, boats, and other watercraft that require reliable one-way water drainage.

Key Features:

  • Prevents backwash and water intrusion through scupper holes
  • Constructed from chemical-resistant materials for long-lasting durability in marine environments
  • Thermoplastic flapper valve provides reliable one-way flow operation
  • Double barb design ensures tight, leak-free hose connections
  • Black finish resists UV degradation

This inline scupper valve is designed for use with 1-1/2 inch hose and installs easily into existing scupper drain lines. The flapper valve automatically closes to prevent water from entering the boat while allowing drainage water to flow out freely. The chemical-resistant construction withstands exposure to saltwater, fuel, oil, and cleaning products commonly found in marine applications.

great service

I sent my order for some comp cams lifters on Monday 1-16-2012 at around 8:30 and the Item was still shipped on the next day Tuesday. This was awesome. I received my product on 1-19-2012. They have had the fastest turn around time that I have ever delt with. I would highly recommend them for your auto parts needs. They also had the cheapest price I could fine, including the shipping fee.<br>I like the fact that they sent me an e-mail that my item had shipped and gave the shipping number for tracking.

Thanks!!!

Fast shipping, packaged with care. Product was exactly what I expected.<br>Overall great experience!

Best Price on the Net for K&N System for my 2012 HEMI RAM. My Order 18270 is shipping today and I can't wait to get it installed!

quick and easy shopping. very good. The only complaint I have is it took too long to receive my order. I ordered Wilwood brakes from California and it took 4 days. It took 10 days to receive my brake master cylinder from Autoplicity.com. I think that is

Like it thanks

HAVE BEEN RESEARCHING THESE SPACERS FOR A WHILE NOW AND AUTOPLICITY HAD THE BEST PRICING AROUND. WILL DEFINITELY DO MORE ORDERS THROUGH THEM.
