Shop John Guest Fittings By Type For Fast, Leak-Free Connections
Browsing by part type speeds selection and reduces costly mismatches on the jobsite. Parts are grouped so buyers can view union connector, union elbow, union tee, and threaded adapter options in one quick scan.
Union Connectors, Union Elbows, & Union Tees
The listings show common sizes and materials with transparent price ranges. A 1/4″ union connector typically starts near $1.66, and union elbows or tees usually fall between about $3.85 and $4.70. Customers can compare price in seconds and review full product specs.
Reducing Unions And Tees To Bridge Mixed Tube Sizes
Options like a 3/8 x 1/4″ reducing union help installers adapt lines without separate adapters. Reducing tee options are shown with dimensions so branch lines fit common RO and beverage tubing.
Elbow Connectors With Stem Fittings And Plug-In Elbows
Elbow connector and plug-in elbow parts simplify direction changes. Stem reducers plus stem fittings let panel-mounted runs stay compact and tidy.
Male And Female NPT/BSP Threaded Adapters
Threaded adapters span 1/8″ to 3/8″ thread sizes. Buyers can choose male or female NPT and BSPP styles to match manifolds and accessories.
“With quick, clear listings, it’s easy to choose the correct part and prevent slow, costly returns.”
| Type | Tube Size | Typical Price |
|---|---|---|
| Union Connector | 1/4″ | $1.66–$2.70 |
| Union elbow | 1/4″ / 3/8″ | $4.05 / $4.50 |
| Reducing union | 3/8 × 1/4″ | $2.29–$3.60 |
| Threaded Adapter (BSPP) | 3/8 × 3/8 | $4.33 |
Why John Guest Push-Fit Fittings Stand Out
For crews focused on speed and reliability, push-to-connect fittings transform how lines are assembled. They pair straightforward assembly with trusted sealing technology so crews use less time per connection.
Tool-Free, Quick Easy Installs With A Secure Lock
With Speedfit and ProLock, quick easy assembly can trim installation time by up to about 40%. Their design grips tubing and pipe with low insertion force and a reliable locking action.
Installers can disconnect without damage, which reduces waste and rework. Because parts can be reused, teams can stock fewer SKUs for typical potable runs.
Leak-Reducing Twist-And-Lock And Superseal Technologies
Twist-and-lock versions boost retention in areas where vibration or movement is common. Superseal incorporates double O-ring seals, making leaks much less likely.
Across 3/8″ to 1″ sizes, ProLock works for hot water and cold water and tolerates higher pressures. Speedfit and ProLock should not be used for gas, fuel oil, or compressed air.
| Product Line | Best use | Key Feature | Typical size |
|---|---|---|---|
| Speedfit | Quick potable runs | Push-to-connect seal for plastic/copper | 1/4″–3/4″ |
| ProLock | Hot water plus higher-pressure lines | Strong lock with high-temperature resilience | 3/8″–1″ |
| Twist-and-Lock / Superseal | Vibration-prone lines | Twist retention with double O-ring sealing | Wide range of OD sizes |
Installation Parts Supply highlights these technologies so customers can view specs and compare price quickly.
Browse Valves And Flow Control To Build Your System
Installation Parts Supply keeps core flow-control pieces for potable water and beverage lines on hand so crews can complete jobs without extra runs to suppliers. Shoppers can skim quick specs and compare price before adding items to the cart.
Tank Valves And Inline Shut-Off Valves
Inline shut-off valves isolate sections for maintenance and routine service. Popular polypro shut-off valves begin at about $5.11 for 3/8″ and roughly $5.71 for 1/4″.
For 1/4″–3/8″ quick-connect sizes, inline valves typically cost about $6.00–$7.00. With quick-connect ports, tank valves simplify tank hookups and keep plumbing steps clean and efficient.
Check Valves For Non-Return Protection
Use a check valve to keep backflow from entering RO systems, coolers, and dispensers. A 3/8″ check valve with a 0.3 psi crack pressure is listed near $9.05.
- Choose john guest inline shut-off valves to isolate sections; price points usually run about $5–$7.
- View full details original for each part to confirm materials, part numbers, and pressure ratings.
- Bulk discounts keep per-connection cost low for repeat builds and stocking spares.
| Component | Typical Price | Notes |
|---|---|---|
| Polypro shut-off valve (3/8″) | $5.11 | Quick-connect |
| Tank valve (quick-connect) | $7.00 | Easy tank hookup |
| Check valve 3/8″, 0.3 psi | $9.05 | Backflow prevention |
Shoppers can quickly view current price and availability, check details original price comparisons, and select valve john guest components that suit their system needs.
Popular Sizes In Stock: 1/4, 3/8, And 1/2 Tube
In most projects, three main tube sizes dominate: 1/4″, 3/8″, and 1/2″, each tailored to specific flow demands. Installation Parts Supply keeps these ready to ship for fast project turnaround.
Ideal Applications For 1/4 Inch Tubing And Fittings
For RO outputs, fridge feeds, and beverage lines, 1/4″ tubing is often the best fit. They save space and fit tight panels.
Union connectors start near $1.66–$2.70, and inline valves at this size commonly run $6–$7.
Where 3/8 Inch Tube Shines In Potable Water Systems
Tube 3/8 works well for longer runs or when a bit more flow and lower pressure drop are needed. A 3/8″ union connector is about $3.60.
Reducing unions like 3/8 x 1/4 ($2.29–$3.60) make transitions simple and future-proof lines.
Using 1/2 Inch Lines For Higher Flow
For higher flow branches and short main runs, 1/2″ tubing offers capacity without too much restriction. You’ll often see a 1/2″ male connector NPTF priced close to $3.27.
- Customers can view current price against original price to catch bulk price breaks.
- Tees, elbows, and valves at each of the three core sizes appear throughout the catalog.
- Full details original show pressure, temperature, and material data for every part number.
| Size | Example Part | Typical Price |
|---|---|---|
| 1/4″ | Union Connector | $1.66–$2.70 |
| 3/8″ | Union connector | $3.60 |
| 1/2″ | Male connector NPTF | $3.27 |
Materials And Finishes Matched To Your Application
Choosing the right material for each joint keeps water quality high and service calls low. Installation Parts Supply guides buyers in matching body materials to water quality, operating temperature, and local code.
Polypropylene And Acetal Options For Potable Water
Polypropylene offers good chemical resistance and strong performance in cold and moderate temps. It’s a cost-effective plastic that cuts overall weight while maintaining reliable sealing.
Acetal is common in quick-connects for its smooth collet action and long wear life. It eases assembly and disassembly for routine service.
Using Brass And Stainless Steel Components As Needed
Brass and stainless offer additional mechanical strength on exposed threaded transitions and high-stress locations. They also address certain code or corrosion requirements.
| Material Type | Best use | Notes |
|---|---|---|
| Polypropylene | Potable water runs | Lightweight, chemical resistant |
| Acetal | Quick-connect fittings | Durable, smooth collet action |
| Brass / Stainless | Threaded transitions and exposed joints | Higher mechanical strength |
Customers can view full details on each SKU, check price and availability, and confirm pipe and tubing compatibility. Bulk discounts often range from ~4% to 20%+, encouraging crews to standardize material kits.

Tips To Install Secure, Push-Fit Connections
With a few small prep steps, push-fit connections can perform like pro-grade joints. Installation Parts Supply recommends a few consistent actions that cut leaks and callbacks. Follow simple habits to keep assembly quick easy and reliable on every run.
Cut Square, Seat Fully, And Use Locking Clips
Cut tube square and deburr the end so the O-ring seats evenly. A poor cut may nick the seal and result in leaks.
Mark the insertion depth first, then push until the tube is fully seated. Check by pulling back gently, then add a lock clip at critical joints for extra retention.
When To Use Twist-And-Lock Or Superseal
Choose twist-and-lock where vibration or movement is expected. It adds retention without slowing quick easy assembly.
Select Superseal for double O-ring protection near equipment or service-critical spots. Use tube supports on soft tubing and hot water lines to keep sealing pressure consistent.
“Cut square, seat fully, and add clips—those steps save time and prevent service calls.”
- Reduce stress on pipe and fittings by avoiding side-loads and supporting long spans.
- Keep parts clean because debris can compromise seals and raise the risk of leaks.
- Reference full details and view rated temperature and pressure before use.
- Keep spare clips and release tools on hand to make field adjustments faster.
