A 3/4-inch water hammer arrestor helps reduce pipe banging by absorbing pressure changes when water flow stops suddenly. For washing machine hoses, the EFIELD, SUNGATOR, and SECKWHALE two-packs offer hose-thread connections; the SharkBite Max is designed for connecting compatible plumbing pipe. The Sioux Chief model is intended for piping systems, but its listed product details do not specify a connection size, so verify sizing before purchase.
| Product | Best For | Connection Style |
|---|---|---|
| EFIELD 2-Pack | Washing machine hose connections | 3/4-inch hose thread |
| Sioux Chief 653-B | Concealed piping installations | Male sweat fittings |
| SharkBite Max UR22632 | Quick pipe connections | Push-to-connect |
| SUNGATOR 2-Pack | Washers, garden hoses, and spigots | 3/4-inch hose thread |

EFIELD 3/4-Inch Stainless Steel Arrestors

The EFIELD set includes two stainless steel arrestors with 3/4-inch female swivel hose thread by 3/4-inch male hose thread connections. The product information lists a maximum working pressure of 250 PSI and says the units can be installed horizontally or vertically.
Best for: Buyers adding arrestors at washing machine supply valves or directly at washing machine hose connections. The two-piece package suits installations that need protection on both hot and cold supplies. Choose this if you need a hose-thread model with flexible installation orientation.
Limitation: These are hose-thread fittings, not push-to-connect fittings for plumbing pipe. Confirm the mating connection and available clearance before ordering.
Sioux Chief 653-B Hydra-Rester

The Sioux Chief Hydra-Rester is a piping-system arrestor with male sweat fittings. Its listed features say the fittings are compatible with press-fitting systems, including Viega process systems, and all push-fitting systems. The product information also says it can be installed in a 2-by-4 wall cavity.
Best for: Plumbing projects that call for an arrestor integrated into a piping system, including installations where a compact wall-cavity fit matters. The product details report lifetime-cycle testing at U.S. testing laboratories for 10,000 shock cycles and factory testing to 500,000 cycles without failure for the 654-C tested model.
Limitation: The supplied details do not state the connection size for this 653-B model. Verify its exact size and fitting requirements before treating it as a 3/4-inch match.
SharkBite Max Push-to-Connect Arrestor

This 3/4-inch brass fitting uses a push-to-connect design to absorb sudden water-pressure changes and reduce banging pipes. The listed compatible pipe materials are PEX, copper, CPVC, PE-RT, and SDR-9 HDPE. The manufacturer describes installation as requiring no soldering, glue, or crimping, including on wet lines.
Best for: Buyers connecting an arrestor to compatible 3/4-inch plumbing pipe who want a push-fit installation rather than a hose-thread connection. It is listed for residential or commercial use, making it the better choice when the plumbing connection—not a washing machine hose—is the priority.
Limitation: This fitting is not described as a washer-hose adapter. Check that the pipe material and connection arrangement match the intended installation.
SUNGATOR 3/4-Inch Straight Arrestors

The SUNGATOR package contains two straight stainless steel 3/4-inch GHT arrestors, sealing tape, and connections for 3/4-inch male and female garden hose thread. Its stated maximum working pressure is 250 PSI, and its maximum temperature is 180°F.
Best for: Households seeking a two-pack for a washer, laundry supply valve, garden hose, or outdoor spigot. The listed use cases make this a versatile option for hose-thread connections beyond laundry equipment.
Limitation: The straight design and hose-thread fittings may not suit installations that require a different connection type or a different fitting shape. Confirm the available space and thread match.
SECKWHALE Brass-Core Arrestor 2-Pack

These straight arrestors connect 3/4-inch GHT male and female fittings and are sold as a two-pack. The product listing identifies C46500 brass construction and states maximum working limits of 250 PSI and 180°F. The stated purpose is to reduce pipe shaking, pounding, and water noise.
Best for: Buyers who want two washer-hose arrestors and specifically value the listed brass material. It is a direct hose-thread option to compare with EFIELD and SUNGATOR.
Limitation: The listed details do not describe pipe-system or push-fit connections. Choose a different connection style if the installation is not based on 3/4-inch hose thread.
Buying Guide: How to Choose a 3/4-Inch Water Hammer Arrestor
Does 3/4 inch mean the same connection on every model?
No. A 3/4-inch measurement can refer to different connection types. The EFIELD, SUNGATOR, and SECKWHALE models list hose-thread connections, while SharkBite lists a push-to-connect fitting for compatible plumbing pipe. Match the fitting type as well as the nominal size. Do not assume that a hose-thread arrestor will connect directly to copper, PEX, or other plumbing pipe.
Is the arrestor for a washing machine or a pipe system?
For a washing machine, check whether the arrestor is made to fit between the supply valve and hose or at the hose connection. For a pipe installation, select a model with a connection style intended for the pipe material and installation method. The Sioux Chief model is a piping-system product, but confirm its exact size before buying.
What pressure and temperature limits should I check?
Compare the arrestor’s stated operating limits with the conditions specified for the plumbing installation. EFIELD lists a maximum working pressure of 250 PSI. SUNGATOR and SECKWHALE list 250 PSI and 180°F. These figures are product limits, not a substitute for checking local requirements or the rest of the plumbing system.
When does a two-pack make sense?
A two-pack may be useful when installing arrestors on both hot and cold washer supplies or at two separate hose-thread locations. Before choosing a package, confirm the number of connection points and whether both sides have matching threads.
Frequently Asked Questions
What does a water hammer arrestor do?
It absorbs sudden pressure changes in a water line to help reduce pipe banging and related noise.
Can I install a hose-thread arrestor on a washing machine?
Use one only when its thread type and connection arrangement match the washer supply and hose. Check the product’s listed connection details first.
Can a 3/4-inch arrestor be installed horizontally?
The EFIELD listing specifically allows horizontal or vertical installation. Check the instructions for any other model before choosing its orientation.
Which model is designed for several pipe materials?
The SharkBite Max listing names PEX, copper, CPVC, PE-RT, and SDR-9 HDPE as compatible pipe materials for its push-to-connect fitting.
