Product Details

The AquaLock 3533-10 is a 1/2 inch CTS (Copper Tube Size) plastic stackable tee fitting from the AquaLock 35-Series push-to-connect plumbing system, formerly known as SeaTech. Designed for fast, reliable connections in marine, RV, and residential plumbing applications, this fitting delivers a secure, leak-free joint without the need for tools or tube inserts.

Key Features:

  • Fits 1/2" CTS tubing — compatible with copper, CPVC, PEX, LDPE, MDPE, HDPE, and polybutylene tubing
  • Tool-free installation — no special tools or tube inserts required
  • Unique O-ring guide feature provides a zero-leak connection every time
  • Unlike barb fittings, connects tubing on the outside, increasing flow capacity
  • Tubing can swivel after connection, even under maximum pressure — ideal for vibrating and dynamic applications
  • Suitable for both hot and cold water applications
  • Rated: 180°F @ 100 PSI / 75°F @ 250 PSI
  • Constructed from polysulfone — a high-performance engineering thermoplastic
  • Lead free construction
  • Recognized by the Uniform Plumbing Code (UPC)
  • Certified to NSF-61, NSF-14, CSA B137.5, ASTM F877, and IGC 188-04c

The stackable design of the 3533-10 allows multiple tees to be connected in series, making it easy to build custom manifolds and branch plumbing runs. Also known as the Watts AquaLock 3533-10 (formerly SeaTech 3533-10), this fitting is a direct drop-in replacement regardless of branding. Watts Ordering Code: 0959097 | UPC: 098268299489.

Fantastic service, and website was very user friendly with insuring correct fitment.

Thx

Ordered it, came it good time, was the right one, put in my car, now it's working like a beauty. Couldn't ask for anything different

FAST AND GOOD PRICE

paid for 2 day delivery and took for days to receive after I was told could not ship to PO Box. That should tell you immediately when you type in ship to address on order form like all other business's do

Great if I order again I will be using the same website again. Thanks

Easy transaction, shipping was lightning fast!

Thanks for having the original part.

It was great
