PT Coupling Hex Steel Lok-Nipple Punch-Lok™ Plated Hose Fittings

Single and Double Groove

PUNCH-LOK® Hex Steel Fittings

Punch-Lok™ single and double groove hose fittings of all types are designed and engineered for use with Punch-Lok™ clamps to make connections which will withstand high pressure services.
The shape of the grooves eliminates damage to the inner wall of the hose.
The Punch-Lok™ clamp brings the hose wall into the grooves with even compression around the fittings.
Carbon steel steam hose fittings are available in sizes ranging from 1/2" to 1" and include tie wires.
Hex Steel Lok-nipples are cut from hexagon shaped cold rolled steel bar stock with full thread and tapered end for easy application.
Lok-Nipples are manufactured in standard iron pipe sizes.
All lok-menders are manufactured in standard iron pipe sizes except for 1/2" and 5/16" where it is necessary to use brass for a good inside diameter fit.
All fittings are plated as standard except for brass fittings.
