Best pipe repair kits for a burst or leaking pipe (2026)
If a pipe splits in a freeze, the first job is to shut off the water. The second is a repair that holds until a plumber can come, or for good if you're handy. This page compares the fixes sold for that in the US: push-fit couplings, epoxy putty, self-fusing tape and fiberglass wrap, by what each fits, the pressure each maker gives and how soon it's usable. We haven't used them ourselves; every figure is the maker's or the listing's.

| Repair kit | Type | Fits | Pressure (maker) | Ready in (maker) | Price |
|---|---|---|---|---|---|
Push-to-connect slip coupling · 1/2 in; copper, PEX, CPVC, PE-RT, HDPE (listing) · Up to 400 psi, 200°F (maker) · Instant; no glue or tools A cut-out section of 1/2 in pipe where you can drain the line first | Push-to-connect slip coupling | 1/2 in; copper, PEX, CPVC, PE-RT, HDPE (listing) | Up to 400 psi, 200°F (maker) | Instant; no glue or tools | |
Our verdictOur verdictResearched A push-to-connect coupling that slides over a repair gap, so a plumber's skills are not needed for a split in 1/2-inch pipe. SharkBite quotes 400 psi and 200 degrees F. It is a real repair rather than a patch, but the pipe must be cut square, cleaned and the water shut off first, and SharkBite's slip-end note says copper only on that end. Best for A cut-out section of 1/2 in pipe where you can drain the line first Good
Worth knowing
Who shouldn't buy it: Don't buy it if you cannot shut off and drain the pipe, or your pipe is not 1/2 inch. | |||||
Self-fusing silicone tape · Pipes and hoses you can wrap (maker) · 950 psi tensile; no pipe rating (maker) · Fuses to itself as you wrap (maker) A fast, no-tools stop for a pinhole or split in a pipe or hose | Self-fusing silicone tape | Pipes and hoses you can wrap (maker) | 950 psi tensile; no pipe rating (maker) | Fuses to itself as you wrap (maker) | |
Our verdictOur verdictResearched A silicone tape that sticks only to itself, so it seals when stretched and wrapped over a leak. The maker quotes 950 psi tensile strength, which is a strength-of-tape figure, not a rating for pipe pressure. A good emergency wrap that holds until a proper repair. Best for A fast, no-tools stop for a pinhole or split in a pipe or hose Good

Who shouldn't buy it: Don't buy it if you need a permanent repair on a high-pressure line. | |||||
Two-part epoxy putty stick · Plugs leaks and cracks in plumbing (maker) · Up to 500 psi (maker) · Sets 25 min, hard in 1 hr (maker) A small pinhole or crack when you cannot take the pipe apart | Two-part epoxy putty stick | Plugs leaks and cracks in plumbing (maker) | Up to 500 psi (maker) | Sets 25 min, hard in 1 hr (maker) | |
Our verdictOur verdictResearched A putty stick you knead and press onto a small leak. J-B Weld says it sets in 25 minutes, is hard in an hour, and holds to 500 psi, even underwater. It suits pinholes and hairline cracks, not a pipe that has burst open. Treat it as a repair to hold until a plumber looks at it. Best for A small pinhole or crack when you cannot take the pipe apart Good
Worth knowing
Who shouldn't buy it: Don't buy it if the pipe has split wide open, or you cannot tolerate a patch rather than a replacement. | |||||
Stainless band repair clamp · 3/8 in pipe; check size, sold per diameter (listing) · Up to 150 psi, 167°F (retailer listings) · Instant; tighten the bolts A pinhole or split in rigid metal pipe that is still in place | Stainless band repair clamp | 3/8 in pipe; check size, sold per diameter (listing) | Up to 150 psi, 167°F (retailer listings) | Instant; tighten the bolts | |
Our verdictOur verdictResearched A stainless band that bolts around a leaking section of pipe and squeezes a seal over it, with no cutting needed. Retailer pages for the B&K line give 150 psi and 167 degrees F, which covers normal house pressure but not every hot line. It only works on the one pipe size printed on the listing, and 3/8 inch is a small size, so check the listing for your pipe before ordering. Best for A pinhole or split in rigid metal pipe that is still in place Good
Worth knowing
Who shouldn't buy it: Don't buy it if your pipe is another size, or the split runs along several inches of pipe. | |||||
Water-activated fiberglass wrap · Pipes and other items you can wrap (listing) · 60 psi (listing) · About 10-15 min (listing) Low-pressure leaks and repairs to hoses and drain lines | Water-activated fiberglass wrap | Pipes and other items you can wrap (listing) | 60 psi (listing) | About 10-15 min (listing) | |
Our verdictOur verdictResearched A fiberglass wrap you wet, wrap around the damage and let harden. The listing quotes only 60 psi, which is below typical house water pressure, so it suits drain, hose and low-pressure fixes better than a supply line. Best for Low-pressure leaks and repairs to hoses and drain lines Good
Worth knowing
Who shouldn't buy it: Don't buy it if you need to fix a pressurized water supply line. | |||||

Before you buy
Shut off the water first.
Find your main shutoff valve now and make sure it turns. Open a faucet below the leak to drain the line before you work on it.
Push-fit couplings are the strongest DIY fix: cut out the split section and push the fitting on.
Match the coupling to your pipe type and size (copper, PEX, CPVC) and use the depth marks in the instructions.
Tape and wraps for a fast stopgap.
Self-fusing silicone tape or a fiberglass wrap can stop a pinhole or small split long enough to get help. Read the pressure figures carefully: Rescue Tape's 950 psi is the tape's tensile strength, not a pipe rating, and FiberFix lists 60 psi, so treat both as temporary on a pressurized line.
Epoxy putty is for pinholes and fittings.
Most need the pipe dry and take time to cure, so read the cure time in the table.
Keep the kit with a flashlight, towels and a bucket where you can reach them in the dark.
We verify every product's specifications against at least two independent sources, re-check its US price and stock on a schedule where we can track it automatically, and cross-check safety-relevant claims against official guidance. Every review is labeled Researched or Used and reviewed by us: where we've bought a product, or been sent it free, and used it ourselves, its review says which; where we haven't, our verdict is a considered spec-and-evidence comparison, not a hands-on test.

Common questions
What should I do if a pipe bursts?
Shut off the main water valve, turn off electricity to the area if water is near outlets or appliances and you can do it safely, open a faucet to drain the line, then repair or call a plumber. If you can't thaw your pipes or they've broken open, CDC says to use bottled water or get water from a neighbor's home.
Can I fix a burst pipe myself?
A small leak, yes, with a clamp, tape or putty as a stopgap. A split pipe needs the damaged section cut out and joined with a coupling, which many homeowners can do on copper or PEX with a push-fit fitting. If the break is inside a wall or you're unsure, call a licensed plumber.
How do I thaw a frozen pipe safely?
The Red Cross says to keep the faucet open and apply heat with "an electric heating pad wrapped around the pipe, an electric hair dryer, a portable space heater (kept away from flammable materials), or by wrapping pipes with towels soaked in hot water." Never use an open flame.
Do pipe repair tapes really work?
Self-fusing silicone tape bonds to itself, not the pipe, and is sold for emergency leaks. It's a stopgap; plan a proper repair.
