GREPSPUD 2 Pair Glad Hands Kit with 12pcs Rubber Seals

GREPSPUD's kit delivers two pairs of color-coded glad hands plus 12 spare rubber seals for reliable, leak-resistant trailer air connections.

This replacement kit supplies both service (blue) and emergency (red) glad hands built from corrosion-resistant aluminum, with precision-machined ports and high-quality rubber gaskets. The set is made to match common OEM fittings and includes extra O-rings so you can restore tight seals quickly when wear appears. It’s intended for heavy-duty semi truck air lines where secure pneumatic coupling is critical.

How does this kit stop air leaks on trailer lines?

The glad hands use CNC-machined threads and smooth port surfaces for accurate mating and a tight fit. Each connection includes durable rubber gaskets that resist aging and corrosion, maintaining airtight contact under pressure. Replacing worn seals is the fastest way to eliminate slow leaks.

• Precision-cut 1/2" NPT ports that seat evenly
• High-quality rubber gaskets engineered for long life
• Includes 12 extra seals so you can swap worn parts immediately

Are these glad hands tough enough for commercial use?

Yes—the housings are cast from heavy-duty aluminum and fitted with high-strength steel clamp plates plus anti-rust nuts. That combination keeps the glad hands clamped under high air pressure and resists road corrosion, extending service life. Color-coded bodies speed identification during maintenance or hookup.

• Durable aluminum bodies for corrosion resistance
• Steel clamp plates and rust-resistant fasteners for secure mounting
• Red (emergency) and blue (service) for quick visual identification

Will these fit my truck and trailer connections?

The kit follows SAE-style dimensions and is compatible with many common manufacturers’ parts, designed to connect rapidly to standard trailer air lines. It replaces numerous OEM part numbers and matches the polarized (service/emergency) or universal configurations found across fleets. Double-check thread and port compatibility for a perfect match.

• Connect size: 1/2" NPT port and standard glad hand dimensions
• Compatible with many Phillips, Tectran, Velvac, Bendix replacements
• Suitable for both service and emergency line mounting

How easy is installation and ongoing maintenance?

Installation is straightforward: remove the worn glad hand, install the clamp plate and nut, and tighten to seat the gasket. The included 12 extra rubber seals mean you won’t be left waiting on parts; swapping a gasket takes minutes with basic hand tools. Regular inspection and timely gasket replacement keeps your system leak-free.

• Simple bolt-on replacement using standard wrenches
• 12 spare O-rings included for quick on-vehicle repairs
• Packaged in neat boxes for organized storage and serviceability
