1) (10Pk) PressKingG 3/4″ 90 Degree Elbow Fitting

Best for tight turn requirements in 3/4-inch gas piping. This elbow is designed for Mega Type press gas fittings and includes an HNBR seal ring for secure sealing. It is CSA certified and suitable for industrial, commercial, and residential gas or fuel oil applications. Not approved for potable water. This bulk option is ideal when multiple elbows are needed in a layout with consistent performance expectations.
Who it’s best for: installers needing multiple 3/4-inch elbows with consistent sealing characteristics in gas lines. Limitations: not suitable for drinking water systems; ensure compatibility with Mega Type fittings in your system.
2) (1Pk) PressKingG 3/4″ Press x Press Gas Tee

A versatile Tee fitting for branching gas lines from a main run. The Mega Type press connection paired with an HNBR seal ensures robust performance in gas piping. CSA certified for industrial, commercial, and residential use. Not for potable water.
Who it’s best for: projects needing a reliable branching point without compromising line integrity. Choose this if your layout requires multiple branch paths. Caution: verify that the Tee orientation aligns with your pipe run to avoid rework.
3) (1Pk) PressKingG 3/4″ Slip Coupling No Stop

Slip coupling without a stop provides flexibility for minor length adjustments in gas pipelines. The 3/4-inch size with Mega Type connection supports quick, secure presses with an HNBR seal and CSA certification. For industrial, commercial, and residential gas uses; not for potable water.
Who it’s best for: installers needing a little extra length adjustability in a gas run. Better for projects where precise length matching is difficult. Limitation: avoid use with potable water systems.
4) (1Pk) PressKingG 1/2″ MIP Carbon Steel Male Adapter

This male adapter converts Mega Type press connections to male iron pipe threads. It is intended for mechanical and fire sprinkler systems. It carries a seal material (EPDM) and CSA/industrial use statements. Not approved for potable water or gas lines. Use in systems requiring threaded-to-press transitions.
Who it’s best for: projects needing a transition from press-to-threaded piping in sprinkler or mechanical installations. Caution: verify system compatibility with EPDM seals and avoid mixing with potable water or gas lines.
5) (1Pk) PressKingG 1/2″ Coupling With Stop

Coupling with stop provides a straightforward join in gas piping with a secure seal. The 1/2-inch size is suited for smaller segments of Mega Type gas piping. CSA certified for industrial, commercial, and residential applications. Not approved for potable water.
Who it’s best for: builds where a reliable 1/2-inch coupling is needed with a stop to prevent movement. Limitation: not for potable water, ensure gas compatibility with Mega Type fittings.
Buying Guide
What matters most when choosing carbon steel press fittings for gas?
Material and certification: Look for CSA certification for gas applications and carbon steel construction for durability. HNBR seals are common in gas fittings for reliable sealing.
Which fitting type should I use?
- Elbows: for turning corners in tight spaces.
- Tees: to branch lines without rework.
- Slip couplings: for minor length adjustments.
- Adapters: to connect to threaded piping or different systems.
- Couplings with stop: secure joints with adjustable spacing.
What are the installation caveats?
- Not approved for potable water; use only in gas or oil systems as specified.
- Ensure Mega Type press connections are compatible with your piping brand.
- Follow local codes and CSA/UL guidelines for gas installations.
How to compare options quickly?
- Elbow vs. Tee: choose based on flow direction needs.
- Size: ensure matching to pipe diameter (e.g., 1/2″ vs 3/4″).
- Seals: HNBR vs EPDM; HNBR is common in gas fittings, EPDM typically for sprinkler systems.
Maintenance and safety considerations
- Inspect joints for signs of seal degradation during service life.
- Schedule periodic checks in high-pressure gas lines and follow safety protocols for press fittings.
