Extend Valve Life with Repair Kits

Valve repair kits provide a cost-effective way to refurbish your valves, replacing worn components to restore functionality without the need for full valve replacement.

Specialized Gate Valve Repair Kits

Designed specifically for gate valves, our gate valve repair kits include all necessary parts like seals and gaskets to bring your valve back to peak performance.

Ball Valve Repair Kits for Smooth Operation

Our ball valve repair kits help you quickly replace crucial parts, ensuring your ball valves maintain a tight seal and operate smoothly over time.

Gate Valve Kit vs. Ball Valve Kit: What's Inside

Gate and ball valve repair kits contain different replacement components because each valve type has a unique internal design. The table below outlines the typical parts included in each type of repair kit. 


Kit Type

Typical Contents

Gate valve repair kit

Gate, seat, surrounding seals, packing, bonnet gaskets

Ball valve repair kit

Seats, O-rings, gaskets, upper/lower bearings; comprehensive kits also include a replacement ball

 

Repair Kit vs. Full Valve Replacement

While many valve issues can be resolved with a repair kit, some situations require replacing the entire valve. The comparison below highlights the key differences to help you determine which option is more appropriate for your application.

Repair Kit

Full Valve Replacement

Replaces worn internal components

Replaces the entire valve assembly

Lower cost

Higher upfront cost

Faster maintenance when the valve body is intact

Required if the valve body is cracked or severely damaged

Extends the life of an existing valve

Best for obsolete or irreparable valves

Save Time and Reduce Costs

Choosing repair kits helps avoid expensive downtime and full valve replacements, making maintenance simpler and more affordable.

Maintain System Efficiency

Regular use of quality repair kits keeps valves functioning properly, helping your entire system run efficiently and preventing leaks or failures.

Signs Your Valve May Need a Repair Kit

Common signs that a valve may benefit from a repair kit include leaks around the stem or body, increased operating resistance, difficulty achieving a complete shutoff, or worn internal seals. If the valve body remains structurally sound, replacing wear components with the correct repair kit can often restore reliable performance and extend the service life of the valve without requiring a full replacement.

Frequently Asked Questions

Typical kits for gate or ball valves contain parts that wear out over time—like O-rings, seats, seals, gaskets, diaphragms, stem bushings, and packing. Some ball valve kits even include a replacement ball, bearings, and stem components.

Repairing saves money and reduces waste. Valve kits let you replace only worn parts, restoring the valve’s performance and extending its lifespan - especially cost-effective for hard-to-replace valves or larger industrial units.

Yes - minor and major gate valve repair kits are available, usually including components like gate, seat, surrounding seals, packing, and bonnet gaskets.

Ball valve kits often include:

  • Seats, O-rings, gaskets.
  • Bearings (upper and lower).
  • A replacement ball (especially in comprehensive kits).

They can match the valve’s pressure rating and body material for proper fit.

Match the kit to your valve’s brand, model, material (PVC, brass, steel), and size. Some kits are designed for True Union ball valves, which allow full cartridge swaps without removing the body.

Annually inspect valves for leaks or stiffness. Replace seals and seats if performance declines. Gate valves can be freed from corrosion; ball valves restored to tight shut-off with repairs.

Yes - many manufacturers offer individual parts like O-rings, seats, springs, bonnet gaskets, and seals, so you can repair just what’s worn instead of using a full kit.

A True Union valve has union fittings on both sides of the body, letting you unscrew the valve from the pipeline without cutting it. This makes it possible to swap the entire internal cartridge (ball, seats, seals) as one assembly, faster than repairing components in place, and is why True Union-specific rebuild kits are sold separately from standard ball valve kits.

A repair kit is usually enough if the valve body itself is intact, no cracks, corrosion through the housing, or stripped threads, and the problem is limited to wear parts like seals, seats, or the ball/gate. If the body is cracked, the handle mechanism is broken, or the valve is an older style with no repair parts still manufactured for it, full replacement is more reliable and often cheaper than sourcing obsolete parts.
